Outline of Final Research Achievements

With this grant, we could redevelop database of 0.1 billion galaxies detected with our deep-space multi-wavelength surveys in which their redshifts, stellar masses, star formation rates, and dust masses were re-derived from an analysis of their spectral energy distributions. We also reclassified ~1000 infrared galaxies into star-formation dominate, active galactic nuclei dominate, and their co-existing populations with their spectral energy distributions, and derive the accretion rates on to the central massive black hole for AGN galaxies in which the AGN tend to suppress star formation in the hosts. The existence of the AGNs and star-forming activities in these galaxies could be confirmed with the follow-up Chandra and JVLA observations. Even though we could obtain above astronomical understandings from new multi-wavelength data, we should still left statistical causal inference analysis due to the observational errors as future works.
