We investigate the relative importance of starbursts and active galactic nuclei (AGN) in nuclear activities of ultraluminous infrared galaxies (ULIRGs) based on chemodynamical simulations combined with spectrophotometric synthesis codes. We numerically investigate both the gas accretion rates (ARs; m acc ) on to supermassive black holes (SMBHs) and the star formation rates (SFRs; m sf ) in ULIRGs formed by gas-rich galaxy mergers and thereby discuss what powers ULIRGs. ...
