    We have proposed a new technology to reduce the propagation loss of waveguide for the receiver of the millimeter to terahertz band radio telescopes and have carried out the demonstration experiment to confirm an availability of it. In this work, we made a rectangular waveguide using superconducting material, measured its propagation characteristics, and compared with 3D electromagnetic field analysis. As a main result, significantly small propagation loss of the superconducting waveguide relative to the normal metal waveguides was found around 100 GHz. We have successfully established the manufacturing method, clarified the propagation mode, and confirmed the potency of the superconducting waveguide.

    We have developed the multi-beam, multi-band, and low noise receiver system to realize a next-generation millimeter-wave spectroradiometer for observing physical/chemical changes in the middle atmosphere. In this work, MMIC superconducting planar type receiver circuit, wide-band superconducting heterodyne mixer, frequency tunable band-pass filter, and frequency modulating local oscillator as a new observation method were developed. Moreover, a test bench receiver system for applying the above newly developed hardware devices and observation software was constructed in our laboratory. We have successfully solved various engineering issues to develop the next-generation millimeter-wave spectroradiometer for a high-sensitivity monitoring system of the atmospheric environment.

    This study aims to understand the influence of energetic particle precipitation (EPP) on the global atmospheric environment from the stratosphere to the lower thermosphere through simultaneous observations from Syowa Station in the Antarctic region and the EISCAT Tromsoe site in the Arctic region. By introducing new technologies, we aimed to expand the range of observational information and improve data quality.
    Due to the COVID19 that prevented us from traveling to the Arctic region, we could not complete the observational research as we originally planned, but we succeeded in installing a multi-frequency millimeter-wave spectrometer and a spectral riometer at Syowa Station and began observations. In particular, the uniquely developed multi-frequency millimeter-wave spectrometer using a waveguide-type frequency multiplexer realized the world's first simultaneous ground-based observations of O3, NO, CO, and HO2 in millimeter waves.

  5. Molecular abundance and distribution of the active galaxy with imaging line survey observations

    About 200 molecular species have been detected in interstellar space. So far "line survey observations" have been carried out to observe molecular lines in unbiased way along the frequency axis. This is a powerful method to study physical and chemical conditions of interstellar matter. Here we applied this method to the galaxy NGC 1068 with the ALMA telescope to study the galaxy with an active galactic nucleus (AGN).
    As a result, we found molecules with enhanced intensity (HCN etc.) in the gas around the AGN (CND), by comparing gas in the CND and in regions where many high-mass stars are formed. These results suggest that the CND is affected by X-ray radiation from the AGN, and/or that the CND is in high-temperature owing to shock wave.
