Description

We have been studying the star-Formation and AGN activities in galaxies up to z~2, which were detected with the AKARI in some Subaru survey fields. As recently reported in Hanami et al. (2012; PASJ, 64, 70), the AKARI/IRC Mid-InfraRed (MIR) multiband photometry is effective not only to distinguish between the star-forming and AGN activities, but also estimate their dust-obscured SFRs and luminosities of dusty tori around hidden AGNs since it continuously covers from 8 to 20 micro-meter and detect the PAH features. We had found some trends as their SFRs were possibly quenched with AGNs around z~1. We could also detect [OII] emissions from the sub-populations around z~0.9 in the AKARI LIRGs with a narrow-band filter at 0.711 $\mu$m (NB711), which can derive their SFR(OII) for studying the relation between the SF activities and the geometries of neutral dusty and ionized components traced with MIR and NB711 detected emissions, respectively.
