    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.
