| Research Abstract |
We studied the star-formation and AGN activity of massive galaxies in the redshift range z=0.4-2, which were detected in a deep survey field using Subaru telescope. From them, we had selected ~1000 Luminous InfraRed (IR) Galaxies (LIRGs) and classified them into three populations; starbursts, starbursts coexisting with AGNs, and AGN-dominants. Super Massive Black Holes (SMBH) could already have grown in the LIRGs with AGNs at z>1.2.
