Description
Summary:By combining the 0.12 deg(2) F814W Hubble Space Telescope (HST) and Spitzer MIPS 24 km imaging in the First Look Survey (FLS), we [unk] increase in the pair fraction for MIPS 24 km detected, optically selected close pairs, with a pair fraction of 0.25 c 0.10 at z 6 1, in contrast addition, 24 km detected galaxies with fluxes .0.1 mJy are on average 5 times more likely to be in a close galaxy pair in the range 0.2 [unk] mergers) are responsible for 27% c 9% of the IR luminosity density resulting from star formation at z 6 1, while morphologically classified formation rate density at z 6 1 can be attributed to galaxies at some stage of a major merger or interaction. We argue that close [unk] universe at z > 0.7.
