Abstract

We present deep Ks83 μJy (the ~80% completeness limit of the Spitzer/GTO 24 μm catalog); 36% of our galaxies have spectroscopic redshifts (mostly at z~1.5. We determine the existence of a bump in the redshift distribution at z~1.9, indicating the presence of a significant population of galaxies with PAH emission at these redshifts. The 24 μm galaxy population ranges from sources with intermediate luminosities (1010 Lsolar~1011 Msolar) hyperluminous galaxies (LIR>1012 Lsolar) at redshifts z~2-3. Massive star-forming galaxies at redshifts 2500 Msolar yr-1), and some of them are able to construct a mass of ~1010-1011 Msolar in a single burst lifetime (~0.01-0.1 Gyr). At lower redshifts z
