Research Abstract

We have performed systematic multi-wavelengths searches for elusive buried mass-accreting supermassive blackholes (=active galactic nuclei ; AGNs) in luminous infrared galaxies, using AKARI, Spitzer, Nobeyama Millimeter Array, and ASTE sub-millimeter telescope. We quantitatively estimated the energetic importance of buried AGNs and found that buried AGNs become more important energetically with increasing galaxy infrared luminosity, observationally suggesting that the AGN-starburst connections are luminosity dependent.
