    We present the first weak-lensing mass calibration and X-ray scaling relations of galaxy clusters and groups selected in the eROSITA Final Equatorial Depth Survey (eFEDS) observed by Spectrum Roentgen Gamma/eROSITA over a contiguous footprint with an area of 140 deg2, using the three-year (S19A) weak-lensing data from the Hyper Suprime-Cam (HSC) Subaru Strategic Program survey. In this work, we study a sample of 434 optically confirmed galaxy clusters (and groups) at redshift 0.01 1.3 with a median of 0.35, of which 313 systems are uniformly covered by the HSC survey to enable the extraction of the weak-lensing shear observable. In a Bayesian population modeling, we perform a blind analysis for the weak-lensing mass calibration by simultaneously modeling the observed count rate η and the shear profile g+ of individual clusters through the count-rate-to-mass-and-redshift (η-M500-z) relation and the weak-lensing-mass-to-mass-and-redshift (MWL-M500-z) relation, respectively, while accounting for the bias in these observables using simulation-based calibrations. As a result, the count-rate-inferred and lensing-calibrated cluster mass is obtained from the joint modeling of the scaling relations, as the ensemble mass spanning a range of 1013h-1M M500 with a median of for the eFEDS sample. With the mass calibration, we further model the X-ray observable-to-mass-and-redshift relations, including the rest-frame soft-band and bolometric luminosity (LX and Lb), the emission-weighted temperature TX, the mass of intra-cluster medium Mg, and the mass proxy YX, which is the product of TX and Mg. Except for LX with a steeper dependence on the cluster mass at a statistically significant level, we find that the other X-ray scaling relations all show a mass trend that is statistically consistent with the self-similar prediction at a level of Meanwhile, all these scaling relations show no significant deviation from the self-similarity in their redshift scaling. Moreover, no significant redshift-dependent mass trend is present. This work demonstrates the synergy between the eROSITA and HSC surveys in preparation for the forthcoming first-year eROSITA cluster cosmology.

    Context. The eFEDS survey is a proof-of-concept mini-survey designed to demonstrate the survey science capabilities of SRG/eROSITA. It covers an area of 140 deg2 where ~540 galaxy clusters have been detected out to a redshift of 1.3. The eFEDS field is partly embedded in the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP) S19A data release, which covers ~510 deg2, containing approximately 36 million galaxies. This galaxy catalogue has been used to construct a sample of ~180 shear-selected galaxy clusters. The common area to both surveys covers about 90 deg2, making it an ideal region to study galaxy clusters selected in different ways. Aims. The aim of this work is to investigate the effects of selection methods in the galaxy cluster detection by comparing the X-ray selected, eFEDS, and the shear-selected, HSC-SSP S19A, galaxy cluster samples. There are 25 shear-selected clusters in the eFEDS fooprint. Methods. The relation between X-ray bolometric luminosity and weak-lensing mass is investigated (Lbol - M relation), comparing this relation derived from a shear-selected cluster sample to the relation obtained from an X-ray selected sample. Moreover, the dynamical state of the shear-selected clusters is investigated and compared to the X-ray selected sample using X-ray morphological parameters and galaxy distribution. Results. The normalisation of the Lbol â ? ? M relation of the X-ray selected and shear-selected samples is consistent within 1Ï ? -. Moreover, the dynamical state and merger fraction of the shear-selected clusters is not different from the X-ray selected ones. Four shear-selected clusters are undetected in X-rays. A close inspection reveals that one is the result of projection effects, while the other three have an X-ray flux below the ultimate eROSITA detection limit. Finally, 43% of the shear-selected clusters lie in superclusters. Conclusions. Our results indicate that the scaling relation between X-ray bolometric luminosity and true cluster mass of the shear-selected cluster sample is consistent with the eFEDS sample. There is no significant population of X-ray underluminous clusters, indicating that X-ray selected cluster samples are complete and can be used as an accurate cosmological probe.

    Context. In 2019, the eROSITA telescope on board the Russian-German satellite Spectrum-Roentgen-Gamma (SRG) began to perform a deep all-sky X-ray survey with the aim of identifying ~100 000 clusters and groups over the course of four years. As part of its performance verification phase, a ~140 deg2 survey, called eROSITA Final Equatorial-Depth Survey (eFEDS), was performed. With a depth typical of the all-sky survey after four years, it allows tests of tools and methods as well as improved predictions for the all-sky survey. Aims. As part of this effort, a catalog of 542 X-ray selected galaxy group and cluster candidates was compiled. In this paper we present the optical follow-up, with the aim of providing redshifts and cluster confirmation for the full sample. Furthermore, we aim to provide additional information on the dynamical state, richness, and optical center of the clusters. Finally, we aim to evaluate the impact of optical cluster confirmation on the purity and completeness of the X-ray selected sample. Methods. We used optical imaging data from the Hyper Suprime-Cam Subaru Strategic Program and from the Legacy Survey to identify optical counterparts to the X-ray detected cluster candidates. We make use of the multi-component matched filter cluster confirmation tool (MCMF), as well as of the optical cluster finder CAMIRA to derive cluster redshifts and richnesses. MCMF provided the probabilities with which an optical structure would be a chance superposition with the X-ray candidate. These probabilities were used to identify the best optical counterpart as well as to confirm an X-ray candidate as a cluster. The impact of this confirmation process on catalog purity and completeness was estimated using optical to X-ray scaling relations as well as simulations. The resulting catalog was furthermore matched with public group and cluster catalogs. Optical estimators of the cluster dynamical state were constructed based on density maps of the red-sequence galaxies at the cluster redshift. Results. By providing redshift estimates for all 542 candidates, we construct an optically confirmed sample of 477 clusters and groups with a residual contamination of 6%. Of these, 470 (98.5%) are confirmed using MCMF, and 7 systems are added through cross-matching with spectroscopic group catalogs. Using observable-to-observable scaling and the applied confirmation threshold, we predict that 8 ± 2 real systems have been excluded with the MCMF cut required to build this low-contamination sample. This number agrees well with the 7 systems found through cross-matching that were not confirmed with MCMF. The predicted redshift and mass distribution of this catalog agree well with simulations. Thus, we expect that these 477 systems include >99% of all true clusters in the candidate list. Using an MCMF-independent method, we confirm that the catalog contamination of the confirmed subsample is 6 ± 3%. Application of the same method to the full candidate list yields 17 ± 3%, consistent with estimates coming from the fraction of confirmed systems of ~17% and with expectations from simulations of ~20%. We also present a sample of merging cluster candidates based on the derived estimators of the cluster dynamical state.

    We present the results obtained from the full-shape cosmology analysis of the redshift-space power spectra for four galaxy samples of the SDSS-III BOSS DR12 galaxy catalog over 0.2<z<0.75. For the theoretical template, we use an emulator that was built from an ensemble set of N-body simulations, which enables fast and accurate computation of the redshift-space power spectrum of "halos."Combining with the halo occupation distribution to model the galaxy-halo connection, we can compute the redshift-space power spectrum of BOSS-like galaxies in less than a CPU second, for an input model under flat ΛCDM cosmology. In our cosmology inference, we use the monopole, quadrupole, and hexadecapole moments of the redshift-space power spectrum and include seven nuisance parameters, with broad priors, to model uncertainties in the galaxy-halo connection for each galaxy sample, but do not use any information on the abundance of galaxies. We demonstrate a validation of our analysis pipeline using the mock catalogs of BOSS-like galaxies, generated using different recipes of the galaxy-halo connection and including the assembly bias effect. Assuming weak priors on cosmological parameters, except for the BBN prior on ωbh2 and the CMB prior on ns, we show that our model well reproduces the BOSS power spectra. Including the power-spectrum information up to kmax=0.25h Mpc-1, we find ωm=0.301-0.011+0.012, H0=68.2±1.4 km s-1 Mpc-1, and σ8=0.786-0.037+0.036 for the mode and 68% credible interval, after marginalization over galaxy-halo connection parameters. We find little improvement in the cosmological parameters beyond a maximum wavelength kmax≃0.2h Mpc-1 due to the shot noise domination and marginalization of the galaxy-halo connection parameters. Our results are consistent with the Planck CMB results within 1σ statistical uncertainties.

    This paper presents the third data release of the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP), a wide-field multi-band imaging survey with the Subaru 8.2 m telescope. HSC-SSP has three survey layers (Wide, Deep, and UltraDeep) with different area coverages and depths, designed to address a wide array of astrophysical questions. This third release from HSC-SSP includes data from 278 nights of observing time and covers about 670 deg2 in all five broad-band filters (grizy) at the full depth (∼26 mag at 5σ depending on filter) in the Wide layer. If we include partially observed areas, the release covers 1470 deg2. The Deep and UltraDeep layers have ∼ 80% of the originally planned integration times, and are considered done, as we have slightly changed the observing strategy in order to compensate for various time losses. There are a number of updates in the image processing pipeline. Of particular importance is the change in the sky subtraction algorithm; we subtract the sky on small scales before the detection and measurement stages, which has significantly reduced the number of false detections. Thanks to this and other updates, the overall quality of the processed data has improved since the previous release. However, there are limitations in the data (for example, the pipeline is not optimized for crowded fields), and we encourage the user to check the quality assurance plots as well as a list of known issues before exploiting the data.

    We present the galaxy shear catalog that will be used for the three-year cosmological weak gravitational lensing analyses using data from the Wide layer of the Hyper Suprime-Cam (HSC) Subaru Strategic Program (SSP) Survey. The galaxy shapes are measured from the i-band imaging data acquired from 2014 to 2019 and calibrated with image simulations that resemble the observing conditions of the survey based on training galaxy images from the Hubble Space Telescope in the COSMOS region. The catalog covers an area of 433.48 deg2 of the northern sky, split into six fields. The mean i-band seeing is 0″. 59. With conservative galaxy selection criteria (e.g., i-band magnitude brighter than 24.5), the observed raw galaxy number density is 22.9 arcmin-2, and the effective galaxy number density is 19.9 arcmin-2. The calibration removes the galaxy property-dependent shear estimation bias to the level |δm| < 9 × 10-3. The bias residual δm shows no dependence on redshift in the range 0 < z ≤ 3. We define the requirements for cosmological weak-lensing science for this shear catalog, and quantify potential systematics in the catalog using a series of internal null tests for systematics related to point-spread function modelling and shear estimation. A variety of the null tests are statistically consistent with zero or within requirements, but (i) there is evidence for PSF model shape residual correlations; and (ii) star-galaxy shape correlations reveal additive systematics. Both effects become significant on >1° scales and will require mitigation during the inference of cosmological parameters using cosmic shear measurements.

    The faint-end slope of the quasar luminosity function at z ∼6 and its implication on the role of quasars in reionizing the intergalactic medium at early times has been an outstanding problem for some time. The identification of faint high-redshift quasars with luminosities of <1044.5 erg s-1 is challenging. They are rare (few per square degree), and the separation of these unresolved quasars from late-Type stars and compact star-forming galaxies is difficult from ground-based observations alone. In addition, source confusion becomes significant at >25 mag, with ∼1/430% of sources having their flux contaminated by foreground objects when the seeing resolution is ∼1/40″.7. We mitigate these issues by performing a pixel-level joint processing of ground and space-based data from Subaru/Hyper-SuprimeCam (HSC) and Hubble Space Telescope (HST) Advanced Camera for Surveys (ACS). We create a deconfused catalog over the 1.64 deg2 of the COSMOS field, after accounting for spatial varying point-spread functions and astrometric differences between the two data sets. We identify twelve low-luminosity (M UV ∼-21 mag) z > 6 quasar candidates through (i) their red color measured between ACS/F814W and HSC/i band and (ii) their compactness in the space-based data. Nondetections of our candidates in Hubble DASH data argues against contamination from late-Type stars. Our constraints on the faint end of the quasar luminosity function at z ∼6.4 suggest a negligibly small contribution to reionization compared to the star-forming galaxy population. The confirmation of our candidates and the evolution of number density with redshift could provide better insights into how supermassive galaxies grew in the first billion years of cosmic time.

    Lensing without borders is a cross-survey collaboration created to assess the consistency of galaxy-galaxy lensing signals (Δς) across different data sets and to carry out end-to-end tests of systematic errors. We perform a blind comparison of the amplitude of Δς using lens samples from BOSS and six independent lensing surveys. We find good agreement between empirically estimated and reported systematic errors which agree to better than 2.3σ in four lens bins and three radial ranges. For lenses with zL > 0.43 and considering statistical errors, we detect a 3-4σ correlation between lensing amplitude and survey depth. This correlation could arise from the increasing impact at higher redshift of unrecognized galaxy blends on shear calibration and imperfections in photometric redshift calibration. At zL > 0.54, amplitudes may additionally correlate with foreground stellar density. The amplitude of these trends is within survey-defined systematic error budgets that are designed to include known shear and redshift calibration uncertainty. Using a fully empirical and conservative method, we do not find evidence for large unknown systematics. Systematic errors greater than 15 per cent (25 per cent) ruled out in three lens bins at 68 per cent (95 per cent) confidence at z < 0.54. Differences with respect to predictions based on clustering are observed to be at the 20-30 per cent level. Our results therefore suggest that lensing systematics alone are unlikely to fully explain the 'lensing is low' effect at z < 0.54. This analysis demonstrates the power of cross-survey comparisons and provides a promising path for identifying and reducing systematics in future lensing analyses.

    We utilize the galaxy shape catalogue from the first-year data release of the Subaru Hyper Suprime-Cam (HSC) surv e y to study the dark matter content of galaxy groups in the Universe using weak lensing. We use galaxy groups from the Galaxy Mass and Assembly galaxy surv e y in approximately 100 sq. de grees of the sk y that o v erlap with the HSC surv e y as lenses. We restrict our analysis to the 1587 groups with at least five members. We divide these groups into six bins each of group luminosity and group member velocity dispersion and measure the lensing signal with a signal-to-noise ratio of 55 and 51 for these two different selections, respectively. We use a Bayesian halo model framework to infer the halo mass distribution of our groups binned in the two different observable properties and constrain the power-law scaling relation and the scatter between mean halo masses and the two-group observable properties. We obtain a 5 per cent constraint on the amplitude of the scaling relation between halo mass and group luminosity with (M) = (0.81 ±0.04) ×10 14 h −1 M ⊙for L grp = 10 11.5 h −2 L ⊙, and a power-law index of α= 1.01 ±0.07. We constrain the amplitude of the scaling relation between halo mass and velocity dispersion to be (M) = (0.93 ±0.05) ×10 14 h −1 M ⊙for σ= 500 km s −1 and a power-law index to be α= 1.52 ±0.10. Ho we ver, these scaling relations are sensitive to the exact cuts applied to the number of group members. Comparisons with similar scaling relations from the literature show that our results are consistent and have significantly reduced errors.

    We present the v1.0 release of CLMM, an open source python library for the estimation of the weak lensing masses of clusters of galaxies. CLMM is designed as a stand-alone toolkit of building blocks to enable end-to-end analysis pipeline validation for upcoming cluster cosmology analyses such as the ones that will be performed by the Vera C. Rubin Legacy Survey of Space and Time-Dark Energy Science Collaboration (LSST-DESC). Its purpose is to serve as a flexible, easy-to-install, and easy-to-use interface for both weak lensing simulators and observers and can be applied to real and mock data to study the systematics affecting weak lensing mass reconstruction. At the core of CLMM are routines to model the weak lensing shear signal given the underlying mass distribution of galaxy clusters and a set of data operations to prepare the corresponding data vectors. The theoretical predictions rely on existing software, used as backends in the code, that have been thoroughly tested and cross-checked. Combined theoretical predictions and data can be used to constrain the mass distribution of galaxy clusters as demonstrated in a suite of example Jupyter Notebooks shipped with the software and also available in the extensive online documentation.

    We simulate the scientific performance of the Nancy Grace Roman Space Telescope High Latitude Survey (HLS) on dark energy and modified gravity. The 1.6-yr HLS Reference survey is currently envisioned to image 2000 deg2 in multiple bands to a depth of ∼26.5 in Y, J, H and to cover the same area with slit-less spectroscopy beyond z = 3. The combination of deep, multiband photometry and deep spectroscopy will allow scientists to measure the growth and geometry of the Universe through a variety of cosmological probes (e.g. weak lensing, galaxy clusters, galaxy clustering, BAO, Type Ia supernova) and, equally, it will allow an exquisite control of observational and astrophysical systematic effects. In this paper, we explore multiprobe strategies that can be implemented, given the telescope's instrument capabilities. We model cosmological probes individually and jointly and account for correlated systematics and statistical uncertainties due to the higher order moments of the density field. We explore different levels of observational systematics for the HLS survey (photo-z and shear calibration) and ultimately run a joint likelihood analysis in N-dim parameter space. We find that the HLS reference survey alone can achieve a standard dark energy FoM of >300 when including all probes. This assumes no information from external data sets, we assume a flat universe however, and includes realistic assumptions for systematics. Our study of the HLS reference survey should be seen as part of a future community-driven effort to simulate and optimize the science return of the Roman Space Telescope.

    We explore synergies between the Nancy Grace Roman Space Telescope and the Vera Rubin Observatory's Legacy Survey of Space and Time (LSST). Specifically, we consider scenarios where the currently envisioned survey strategy for the Roman Space Telescope's High Latitude Survey (HLS reference), i.e. 2000 deg2 in four narrow photometric bands is altered in favour of a strategy of rapid coverage of the LSST area (to full LSST depth) in one band. We find that in only five months, a survey in the W-band can cover the full LSST survey area providing high-resolution imaging for >95 per cent of the LSST Year 10 gold galaxy sample. We explore a second, more ambitious scenario where the Roman Space Telescope spends 1.5 yr covering the LSST area. For this second scenario, we quantify the constraining power on dark energy equation-of-state parameters from a joint weak lensing and galaxy clustering analysis. Our survey simulations are based on the Roman Space Telescope exposure-time calculator and redshift distributions from the CANDELS catalogue. Our statistical uncertainties account for higher order correlations of the density field, and we include a wide range of systematic effects, such as uncertainties in shape and redshift measurements, and modelling uncertainties of astrophysical systematics, such as galaxy bias, intrinsic galaxy alignment, and baryonic physics. We find a significant increase in constraining power for the joint LSST + HLS wide survey compared to LSST Y10 (FoMHLSwide = 2.4 FoMLSST) and compared to LSST + HLS (FoMHLSwide = 5.5 FoMHLSref).

    Using photometrically selected galaxies from the Hyper Suprime-Cam (HSC) survey, we measure the stellar-mass density profiles for satellite galaxies around isolated central galaxies (ICGs) from SDSS/DR7 at z ~ 0.1. By stacking HSC images, we also measure the projected stellar-mass density profiles for ICGs and their stellar halos. The total mass distributions are further measured from HSC weak-lensing signals. ICGs dominate within ~0.15 times the halo virial radius (0.15 R200). The stellar mass versus total mass fractions drop with the increase in projected distance up to ~0.15 R200, beyond which they are less than 1% while staying almost constant. The integrated stellar mass in satellites is proportional to the virial mass of the host halo, M200, for ICGs more massive than 1010.5Me, i.e., M*,sat ?M200, whereas the relation between the stellar mass of ICGs + stellar halos and M200 is close to M ,ICG+diffuse µ M200 1 2*. Below 1010.5Me, the change in M200 is much slower with the decrease in M*,ICG+diffuse. At fixed stellar mass, red ICGs are hosted by more massive dark matter halos and have more satellites. At M200 ~ 1012.7Me, both M*,sat and the fraction of stellar mass in satellites versus total stellar mass, fsat, tend to be marginally higher around blue ICGs. fsat increases with the increase in both M*,ICG+diffuse and M200, and scales more linearly with M200. We provide best-fitting relations to M200 versus M*,ICG+diffuse, M*,sat or M*,ICG+diffuse +M*,sat, and to fsat versus M200 or M*,ICG+diffuse, for red and blue ICGs separately.

    We use the Hyper Suprime-Cam Subaru Strategic Program S19A shape catalog to construct weak lensing shear-selected cluster samples. From aperture mass maps covering ∼510 deg2 created using a truncated Gaussian filter, we construct a catalog of 187 shear-selected clusters that correspond to mass map peaks with signal-to-noise ratio larger than 4.7. Most of the shear-selected clusters have counterparts in optically selected clusters, from which we estimate the purity of the catalog to be higher than 95%. The sample can be expanded to 418 shear-selected clusters with the same signal-to-noise ratio cut by optimizing the shape of the filter function and by combining weak lensing mass maps created with several different background galaxy selections. We argue that dilution and obscuration effects of cluster member galaxies can be mitigated by using background source galaxy samples and adopting a filter function with its inner boundary larger than about 2'. The large samples of shear-selected clusters that are selected without relying on any baryonic tracer are useful for detailed studies of cluster astrophysics and cosmology.

    We present a catalog of 4195 optically confirmed Sunyaev–Zel’dovich (SZ) selected galaxy clusters detected with signal-to-noise ratio >4 in 13,211 deg2 of sky surveyed by the Atacama Cosmology Telescope (ACT). Cluster candidates were selected by applying a multifrequency matched filter to 98 and 150 GHz maps constructed from ACT observations obtained from 2008 to 2018 and confirmed using deep, wide-area optical surveys. The clusters span the redshift range 0.04 < z < 1.91 (median z = 0.52). The catalog contains 222 z > 1 clusters, and a total of 868 systems are new discoveries. Assuming an SZ signal versus mass-scaling relation calibrated from X-ray observations, the sample has a 90% completeness mass limit of M500c > 3.8 × 1014 Me, evaluated at z = 0.5, for clusters detected at signal-to-noise ratio >5 in maps filtered at an angular scale of 2 4. The survey has a large overlap with deep optical weak-lensing surveys that are being used to calibrate the SZ signal mass-scaling relation, such as the Dark Energy Survey (4566 deg2), the Hyper Suprime-Cam Subaru Strategic Program (469 deg2), and the Kilo Degree Survey (825 deg2). We highlight some noteworthy objects in the sample, including potentially projected systems, clusters with strong lensing features, clusters with active central galaxies or star formation, and systems of multiple clusters that may be physically associated. The cluster catalog will be a useful resource for future cosmological analyses and studying the evolution of the intracluster medium and galaxies in massive clusters over the past 10 Gyr.

    We conduct a comprehensive and statistical study of the luminosity functions (LFs) for satellite galaxies, by counting photometric galaxies from HSC, DECaLS, and SDSS around isolated central galaxies (ICGs) and paired galaxies from the SDSS/DR7 spectroscopic sample. Results of different surveys show very good agreement. The satellite LFs can be measured down to MV ∼ -10, and for central primary galaxies as small as 8.5 < log10M /M⊙ < 9.2 and 9.2 < log10M /M⊙ < 9.9, which implies there are on average 3-8 satellites with MV < -10 around LMC-mass ICGs. The bright end cutoff of satellite LFs and the satellite abundance are both sensitive to the magnitude gap between the primary and its companions, indicating galaxy systems with larger magnitude gaps are on average hosted by less massive dark matter haloes. By selecting primaries with stellar mass similar to our Milky Way (MW), we discovered that (i) the averaged satellite LFs of ICGs with different magnitude gaps to their companions and of galaxy pairs with different colour or colour combinations all show steeper slopes than the MWsatellite LF; (ii) there are on average more satellites with -15 < MV < -10 than those in our MW; (iii) there are on average 1.5 to 2.5 satellites with MV < -16 around ICGs, consistent with our MW; (iv) even after accounting for the large scatter predicted by numerical simulations, the MW satellite LF is uncommon at MV > -12. Hence, the MWand its satellite system are statistically atypical of our sample of MW-mass systems. In consequence, our MW is not a good representative of other MW-mass galaxies. Strong cosmological implications based on only MW satellites await additional discoveries of fainter satellites in extra-galactic systems. Interestingly, the MW satellite LF is typical among other MW-mass systems within 40 Mpc in the local Universe, perhaps implying the Local Volume is an underdense region.

    We apply the Fourier Power Function Shapelets (FPFS) shear estimator to the first-year data of the Hyper Suprime-Cam survey to construct a shape catalog. The FPFS shear estimator has been demonstrated to have a multiplicative bias less than 1% in the absence of blending, regardless of complexities of galaxy shapes, smears of point spread functions (PSFs), and contamination from noise. The blending bias is calibrated with realistic image simulations, which include the impact of neighboring objects, using the COSMOS Hubble Space Telescope images. Here we carefully test the influence of PSF model residual on the FPFS shear estimation and the uncertainties in the shear calibration. Internal null tests are conducted to characterize potential systematics in the FPFS shape catalog, and the results are compared with those measured using a catalog where the shapes were estimated using the re-Gaussianization algorithms. Furthermore, we compare various weak-lensing measurements between the FPFS shape catalog and the re-Gaussianization shape catalog and conclude that the weak-lensing measurements between these two shape catalogs are consistent with each other within the statistical uncertainty.

    We assess the performance of a perturbation theory inspired method for inferring cosmological parameters from the joint measurements of galaxy-galaxy weak lensing (Δς) and the projected galaxy clustering (wp). To do this, we use a wide variety of mock galaxy catalogs constructed based on a large set of N-body simulations that mimic the Subaru HSC-Y1 and SDSS galaxies and apply the method to the mock signals to address whether to recover the underlying true cosmological parameters in the mocks. We find that, as long as the appropriate scale cuts, 12 and 8h-1 Mpc for Δς and wp, respectively, are adopted, a "minimal-bias"model using the linear bias parameter b1 alone and the nonlinear matter power spectrum can recover the true cosmological parameters (here focused on ωm and σ8) to within the 68% credible interval, for all the mocks we study, including one in which an assembly bias effect is implemented. This is as expected if physical processes inherent in galaxy formation and evolution are confined to local, small scales below the scale cut and thus implies that real-space observables have an advantage in filtering out the impact of small-scale nonlinear effects in parameter estimation, compared to their Fourier-space counterparts. In addition, we find that a theoretical template including the higher-order bias contributions such as nonlinear bias parameter (b2) does not improve the cosmological constraints, but rather leads to a larger parameter bias compared to the baseline b1 method. Another nontrivial finding is that the cosmological parameters are not necessarily recovered, even when the model prediction is used as the input mock signals, as a consequence of marginalization or projection of asymmetric posterior distributions in a multidimensional parameter space, such as the case of the "banana-shaped"distribution in the (ωm,σ8) plane. We also study the performance of alternative observables, ϒ or Y statistic, where the same scale cut for both the weak lensing and the galaxy clustering can be employed thanks to their same sensitivity to the Fourier modes, but do not find a promising advantage of these statistics over the fiducial observables {Δς,wp}.

    We report the weak lensing measurement of filaments between Sloan Digital Sky Survey (SDSS) III/Baryon Oscillation Spectroscopic Survey (BOSS) CMASS galaxy pairs at z ∼ 0.55, using the Subaru Hyper Suprime-Cam (HSC) first-year galaxy shape catalogue. Despite of the small overlap of 140 deg2between these surveys, we detect the filament lensing signal at 3.9Ï significance, which is the highest signal-to-noise lensing measurement of filaments between galaxy-scale haloes at this redshift range. We derive a theoretical prediction and covariance using mock catalogues based on full-sky ray-tracing simulations. We find that the intrinsic scatter of filament properties and the fluctuations in a large-scale structure along the line of sight are the primary component of the covariance and the intrinsic shape noise from source galaxies no longer limits our lensing measurement. This fact demonstrates the statistical power of the HSC survey due to its deep observations and high number density of source galaxies. Our result is consistent with the theoretical prediction and supports the âthickâ™ filament model. As the HSC survey area increases, we will be able to study detailed filament properties such as the dark matter distributions and redshift evolution of filaments.

    We perform an ensemble of N-body simulations with 20483 particles for 101 flat wCDM cosmological models sampled based on a maximin distance sliced Latin hypercube design. By using the halo catalogs extracted at multiple redshifts in the range of z = [0,1.48], we develop Dark Emulator, which enables fast and accurate computations of the halo mass function, halo-matter cross-correlation, and halo autocorrelation as a function of halo masses, redshift, separations, and cosmological models based on principal component analysis and Gaussian process regression for the large-dimensional input and output data vector. We assess the performance of the emulator using a validation set of N-body simulations that are not used in training the emulator. We show that, for typical halos hosting CMASS galaxies in the Sloan Digital Sky Survey, the emulator predicts the halo-matter cross-correlation, relevant for galaxy-galaxy weak lensing, with an accuracy better than 2% and the halo autocorrelation, relevant for galaxy clustering correlation, with an accuracy better than 4%. We give several demonstrations of the emulator. It can be used to study properties of halo mass density profiles such as the concentration-mass relation and splashback radius for different cosmologies. The emulator outputs can be combined with an analytical prescription of halo-galaxy connection, such as the halo occupation distribution at the equation level, instead of using the mock catalogs to make accurate predictions of galaxy clustering statistics, such as galaxy-galaxy weak lensing and the projected correlation function for any model within the wCDM cosmologies, in a few CPU seconds.

    We present the first measurement of cross-correlation between the lensing potential, reconstructed from cosmic microwave background (CMB) polarization data, and the cosmic shear field from galaxy shapes. This measurement is made using data from the Polarbear CMB experiment and the Subaru Hyper Suprime-Cam (HSC) survey. By analyzing an 11 deg2 overlapping region, we reject the null hypothesis at 3.5σ and constrain the amplitude of the cross-spectrum to , where is the amplitude normalized with respect to the Planck 2018 prediction, based on the flat Λ cold dark matter cosmology. The first measurement of this cross-spectrum without relying on CMB temperature measurements is possible owing to the deep Polarbear map with a noise level of ∼6 μK arcmin, as well as the deep HSC data with a high galaxy number density of . We present a detailed study of the systematics budget to show that residual systematics in our results are negligibly small, which demonstrates the future potential of this cross-correlation technique.

    We measure cosmic weak lensing shear power spectra with the Subaru Hyper Suprime- Cam (HSC) survey first-year shear catalog covering 137 deg2 of the sky. Thanks to the high effective galaxy number density of ∼17 arcmin-2, even after conservative cuts such as a magnitude cut of i < 24.5 and photometric redshift cut of 0.3 ≤ z ≤ 1.5, we obtain a high-significance measurement of the cosmic shear power spectra in four tomographic redshift bins, achieving a total signal-to-noise ratio of 16 in the multipole range 300 ≤ ℓ ≤ 1900. We carefully account for various uncertainties in our analysis including the intrinsic alignment of galaxies, scatters and biases in photometric redshifts, residual uncertainties in the shear measurement, and modeling of the matter power spectrum. The accuracy of our power spectrummeasurement method as well as our analytic model of the covariance matrix are tested against realistic mock shear catalogs. For a flat ∧ cold dark matter model, we find S8 ≡ σ8(Ωm/0.3)α = 0.800+0.029-0.028 for α = 0.45 (S8 = 0.780+0.030-0.033 for α = 0.5) from our HSC tomographic cosmic shear analysis alone. In comparison with Planck cosmic microwave background constraints, our results prefer slightly lower values of S8, although metrics such as the Bayesian evidence ratio test do not show significant evidence for discordance between these results. We study the effect of possible additional systematic errors that are unaccounted for in our fiducial cosmic shear analysis, and find that they can shift the best-fit values of S8 by up to ∼0.6 σ in both directions. The full HSC survey data will contain several times more area, and will lead to significantly improved cosmological constraints.

The wide field corrector delivers sharp image of 0.25 arc-sec FWHM in r-band over the entire 1.5 degree (in diameter) field of view. The collimation of the camera with respect to the optical axis of the primary mirror is realized by hexapod actuators whose mechanical accuracy is few microns. As a result, we expect to have seeing limited image most of the time. Expected median seeing is 0.67 arc-sec FWHM in i-band. The sensor is a p-ch fully depleted CCD of 200 micron thickness (2048 x 4096 15 μm square pixel) and we employ 116 of them to pave the 50 cm focal plane. Minimum interval between exposures is roughly 30 seconds including reading out arrays, transferring data to the control computer and saving them to the hard drive. HSC uniquely features the combination of large primary mirror, wide field of view, sharp image and high sensitivity especially in red. This enables accurate shape measurement of faint galaxies which is critical for planned weak lensing survey to probe the nature of dark energy. The system is being assembled now and will see the first light in August 2012. © 2012 SPIE.

    Hyper Suprime-Cam(HSC)isa1GigapixelCCD camerafora wide-fieldgalaxy surveyatthe Subaru8-mTelescope. It will be mounted on the prime focus of the SubaruTelescope and is scheduled to receive its first light in 2012. The primary science is to conduct a weak lensing survey over ∼ 2,000 square degrees. The HSC has a 1.5-degree-diameter fieldofview, 7timeslarger than thatofits predecessor Suprime-Cam.It consistsofalarge corrector lens systemand afocalplane equippedwith116piecesof2kx4kfully depletedCCDs. Combinedwiththesuperbimagequalityand large aperture of the Subaru telescope, the surveyusing HSC can cover a cosmological volume and reach the limiting magnitude of at least one magnitudefainter than the other surveys conducted using 4-m class telescopes. The readout electronics of the HSC consist of two parts: one is the analog front-end electronics (FEE) and the other is the digital back-end electronics (BEE). The FEE is placed in a vacuum dewar together with the CCDs, and processes the analog CCD signal into 16-bit digital data. The BEE is small and light enough to be integrated into the camera unit, and employs three linksofGigabit Ethernetto readouta 2.3-GByte singleexposure within10 secondsatfast readout operation. The readout noise from the electronics is smaller than that from CCDs.

    Hyper Suprime-Cam (HSC) employs 116 pieces of 2k×4k fully-depleted CCD with a total of 464 signal outputs to cover the 1.5 degrees diameter field of view. The readout electronics was designed to achieve ∼5 e of the readout noise and 150000 e of the fullwell capacity with 20 seconds readout time. Although the image size exceeds 2G Bytes, the readout electronics supports the 10 seconds readout time for the entire CCDs continuously. All of the readout electronics and the CCDs have already been installed in the camera dewar. The camera has been built with equipment such as coolers and an ion pump. We report the readout performance of all channels of the electronics extracted from the recent test data. © 2012 SPIE.

    宇宙の加速膨張は現代物理学における最大の謎の一つである。加速膨張は未知の暗黒エネルギーによって引き起こされているとする一方で、アインシュタインの一般相対性理論の修正が必要だとする指摘もある。本研究では、すばる望遠鏡Hyper Suprime-Cam(HSC)による広視野深宇宙撮像銀河サーベイの最終年度のデータを用いて弱重力レンズ効果を測定することで、世界最高精度で宇宙の加速膨張の性質を測定し、暗黒エネルギーの性質及び修正重力理論の兆候に制限を課すことを目指す。そのために、機械学習を用いて観測的系統誤差を低減し、修正重力理論を考慮に入れた弱重力レンズ観測量のモデルを構築する。

    本研究では、すばる望遠鏡の新広視野主焦点カメラHyper Suprime-Cam (HSC)で取得した光赤外波長域のデータと、Advanced Atacama Cosmology Telescope (AdvACT)で取得した宇宙マイクロ波背景放射のデータを組み合わせることにより、近傍から遠方までの銀河団の質量を正確に測定し、各質量・各赤方偏移における銀河団の個数を数え上げることによって、ニュートリノ全質量に制限を付けることを目指す。本研究は、観測的宇宙論と素粒子物理学を、観測・実験の観点から融合させる先駆的研究である。
    本研究計画の目標は、すばる望遠鏡広視野主焦点カメラHyper Suprime-Cam (HSC)や高感度・高分解能高宇宙マイクロ波背景放射サーベイであるPlanck衛星やAdvanced Atacama Cosmology Telescope Polarimeter (AdvACT) 赤方偏移銀河団のデータを組み合わせ、高赤方偏移銀河団の質量関数を測定することによって、ニュートリノ質量和に上限をつけることである。今年度はHSCで発見された高赤方偏移銀河団を用いたPlanck衛星によって測定された宇宙マイクロ波背景放射における重力レンズ効果(以下CMBレンズ効果)の測定を通して、CMB重力レンズ効果測定と理論解釈のためのソフトウェア・パイプラインの開発を行った。また、HSCで発見されたz~4の遠方銀河によるCMB重力レンズ効果をPlanck衛星のデータを用いて測定した。これはこの赤方偏移領域の銀河では世界で初めての暗黒物質分布測定となる。
    来年度は、Planck衛星のデータを用いた銀河団-CMB重力レンズ効果の解析をさらに発展させ、AdvACTのデータを用いてより高い信号雑音比でCMB重力レンズ効果を測定する。これを用いて銀河団質量関数を推定することで、ニュートリノ質量和の上限に制限を付ける。また、今年度測定したz~4の銀河-CMB重力レンズ効果とすでにある同じ銀河サンプルの自己相関関数を組み合わせることにより、この赤方偏移領域の宇宙の大規模構造を用いた宇宙論制限を世界で初めて付けることを目指す。
    今年度は銀河団及び銀河の周りのCMBレンズ効果を測定するソフトウェア・パイプラインの開発を行い、HSCやPlanck衛星のデータを用いてCMBレンズ効果を測定することに成功した。また、測定したCMBレンズ効果を観測データにおけるエイリアシングなどを考慮しながら理論解釈するソフトウェアの開発を行い、来年度に行う宇宙論解析の基盤を整えることができた。
    来年度はAdvACTコラボレーションと協力し、HSCで発見された高赤方偏移銀河団のCMBレンズ効果を測定する。HSCとAdvACTはデータ交換のための協定覚書を締結しており、まだ公開されていない最新のデータを用いることができる。これにより、世界最高精度で高赤方偏移銀河団のCMBレンズ効果を測定することを目指す。また、今年度測定されたz~4の高赤方偏移銀河のCMBレンズ信号と、すでにある自己相関関数の測定を用いて宇宙論に制限を付ける研究を行う。

    本研究の目的は以下の通りである。まず、すばる望遠鏡Hyper Suprime-Camによる可視光撮像銀河サーベイデータに、近赤外撮像データを加えることによって、高赤方偏移の銀河団を同定する。この銀河団サンプルの単位質量あたり・単位体積あたりの個数と弱重力レンズ効果を用いて測定した銀河団質量を用い、ニュートリノ全質量和を制限することである。前年度は、HSCのCOSMOS領域において、Spitzer望遠鏡IRACによる赤外撮像データを組み合わせた解析を行なった。HSCの他の領域に重なるIRACのデータは、COSMOS領域のデータに比べて浅いため、今年度はそれによる測光的赤方偏移への影響を調べ、COSMOS領域以外でも十分に測光的赤方偏移を改善することがわかった。本データ解析遂行のために、大学院生をSpirzerのデータ解析の専門家がいるカリフォルニア工科大学に派遣するなど活発な研究活動を行なった。また、HSCの観測領域と重複するVIKINGサーベイの近赤外データでも測光的赤方偏移が改善するかどうかを調べたが、VIKINGのデータがHSCに比べて相対的に浅いため、残念ながら改善は見られなかった。今後は、2019年前半までのデータを用いて解析されたHSCサーベイデータとIRACの複数のサーベイのデータを組み合わせ、改善した測光的赤方偏移に基づいて高赤方偏移カタログを作成し、先に述べた方法に従ってニュートリノ全質量和を制限する。本若手研究は重複制限により今年度で終了となるが、今後の研究は新たに獲得した基盤(B)に発展的に引き継がれる。

    本研究の目的は、すばる望遠鏡新超広視野主焦点カメラHyper Suprime-Cam (HSC)によるすばる望遠鏡戦略枠サーベイのデータを用いた弱重力レンズ効果の測定を通して、世界最高精度で宇宙の加速膨張の性質に制限を付けることである。本年度は、昨年度に引き続き、Sloan Digital Sky Survey (SDSS) III / Baryon Oscillation Spectroscopic Survey (BOSS)の分光銀河カタログとHSCサーベイ初年度の銀河形状カタログを組み合わせることで、銀河自己相関関数と銀河弱重力レンズ効果を測定することで、宇宙論パラメータに制限を付けるための研究を主に行なった。モック信号を用いて高精度で宇宙論情報を引き出すための理論モデルを構築し、実際のデータを用いて、Dark Energy Surgey (DES), Kilo Degree Survey (KiDS)などの世界の他の競合するサーベイと同等もしくはそれ以上の精度で宇宙論を制限することが可能となった。本解析はブラインド解析を行っており、さらなる系統誤差のテストの後、次年度始めにはブラインドを取り去り、論文を執筆する予定である。
    HSCサーベイ初年度の銀河形状カタログを用いた他の解析としては、高感度・高角度分解能マイクロ波望遠鏡PolarBearで測定された重力レンズ効果とHSCで測定された重力レンズ効果の相互相関を測定する研究を行った。
    昨年度から行ってきた、HSCサーベイ3年目まで銀河形状カタログの作成は、画像解析に問題が見つかったため、サーベイ4年目までのデータを用いた新しい画像解析に基づいた作成を行った。系統誤差のテストはほぼ完了し、来年度始めには画像シミュレーションを用いた銀河形状の補正係数を求め、銀河形状カタログが完成する予定である。

    本年度は、Atacama Cosmology Telescope Polarimeter (ACTPol)が2014年までに取得したデータに基づき、Sunyaev-Zel’dovich (SZ)効果で発見された銀河団のカタログと、すばる望遠鏡Hyper Suprime-Cam(HSC)が2016年までに取得したデータの銀河形状カタログを用いて、銀河団の弱重力レンズ効果の測定を行い、銀河団質量の推定を行った。まず、HSCの銀河形状の系統誤差を精密に評価し、銀河形状カタログを作成した。このカタログはHSCコラボレーション内で広く使われている。宇宙論的な物質の密度揺らぎや各銀河団の個性を考慮に入れた統計誤差を正確にモデル化し、測光的赤方偏移の誤った評価によって引き起こされる系統誤差の評価などを行った。また、測定データをフィットする際に用いる理論モデルとして、ACTPolのSZ銀河団の選択関数や、SZ信号に基づいて推定された質量と弱重力レンズ効果によって測定された真の質量との関係などを組み込んだ理論モデルを構築した。この時に用いる物質分布のプロファイルとして、Navarro-Frenk-White(NFW)プロファイルやバリオン入りのN体シミュレーションに基づいたプロファイルを用いて、理論モデルの不定性を調べる研究を行った。このモデルを測定データにフィットする事により、SZ銀河団質量と真の銀河団質量の間には有意な違いがあり、それは先行研究と整合的であることを示した。重複制限により、本年度が最終年度となったが、以上の研究を通して、本研究の目的であるHSCとACTを用いた銀河団質量関数による宇宙論の制限に必要なツールはほぼ準備できたと言える。

    2014年3月から、すばる望遠鏡超広視野主焦点カメラHyper Suprime-Cam(HSC)による大規模銀河サーベイが始まった。昨年度に引き続き高精度弱重力レンズ効果測定法の開発を進めた。具体的には、銀河の周りの弱重力レンズ信号を計算し、過去の観測の結果と一致することを確かめるなどの研究を行った。

    HSCサーベイとAtacama Cosmology Telecsope(ACT)サーベイのデータを組み合わせて、銀河団計数から宇宙論パラメータを制限する研究の準備として、Canada-France-Hawaii-Telecope CS82サーベイとACTサーベイを組み合わせ、弱重力レンズ効果を用いて銀河団の質量を較正する研究を行った。

    今年度は新たに銀河団のアセンブリ・バイアスの研究を行った。銀河・銀河団は暗黒物質の分布のうち、重力崩壊によって形成されたハローの中に棲んでいる。よって銀河・銀河団の分布は暗黒物質の分布をバイアスして反映している。両者の分布の関係は、従来はハローの質量のみに依存すると考えられてきたが、理論的もしくは数値的な研究によってハローの他の性質にも依存することが指摘されてきた。これをアセンブリ・バイアスという。今回の研究では、Sloan Digital Sky Surveyの銀河団サンプルを、メンバー銀河の中心集中度によって2つのサンプルに分け、銀河団の弱重力レンズ効果と2点相関関数を組み合わせることで、アセンブリ・バイアスを世界で初めて検出した。アセンブリ・バイアスは将来の精密宇宙論の測定において系統誤差となると指摘されており、本研究でアセンブリ・バイアスの理解の第一歩を踏み出したことは大きな意義がある。本研究成果はPhysical Leview Lettersに掲載され、注目論文に選ばれた。
