The talk will be titled: The first 3 Gyr as seen by Spitzer: passive, dusty and star-forming galaxies at z > 2:
We investigate the evolution of massive passive/dusty galaxies with deep near-IR Spitzer imaging from the SMUVS survey. We determine stellar masses, redshifts and dust extinction in ~66000 galaxies at z > 2. We compute galaxy stellar mass functions and find that galaxy downsizing is active down to logM* = 9.7. At z > 6, we measure beta - UV slopes and luminosities and constrain EWs of key rest-frame optical emission lines for ~100 galaixes. We detect the presence of galaxies with EW(Ha) ~1500A and discuss these results in the light of galaxy mass assembly.
