| Description |
We propose a deep PACS imaging survey of a prestigious far-IR survey field, AKARI-Deep field south, which has the lowest cirrus background in the sky and has been observed with most of the major IR and submm telescopes, such as AKARI, Spitzer/MIPS, BLAST and Herschel/HerMES, covering 7-12 deg^2. We also conducted one of the widest and deepest millimetre survey using ASTE/AzTEC within this field, covering 0.25 deg^2. Although there are many (sub)mm survey fields in different parts of the sky, ADF-S has a unique data set from AKARI/IRC at 2.4, 3.2, 4.1, 7, 11, 15 micron, i.e. filling the wavelength gap between Spitzer/IRAC 8 micron and MIPS 24 micron. We utilize this comprehensive mid-IR coverage to identify obscured AGNs and derive the bolometric AGN luminosity, based on the type-independent X-ray-to-mid-IR luminosity relation. PACS photometry is necessary to derive accurate star formation rate (SFR) in starburst-AGN composite system. We investigate the relative importance of AGN in SMGs and other mid-IR selected ULIRGs, as a function of SFR, stellar mass, and redshift. Ultimately, we will determine the role of AGN in galaxy formation and the regulation mechanism for co-evolution of stellar mass assembly and central black hole. Also, deep PACS images allow us to identify millimeter-selected SMGs at very high redshifts, which will be prime targets of ALMA. |
