Herschel/HST studies of ULIRGs at z~2

Jiasheng Huang NAOC/Harvard-Smithsonian

I will presnt a study of large MIPS 24 micron selected sample
of ULIRGs. With the detcetion of this sample in the HerMES survey, we are able to determine their FIR luminosities. The HST NIR imaging of these objects provide the rest-frame optical morphologies. Our study shows that this population contribute dominantly to star formation rate density at z~2.
Their morphologies provide a clue of how these systems are formed.
