Title: A Complete Census of z=1-3 Galaxies in the Subaru Deep Field

Abstract: The Subaru Deep Field (SDF) is one of the deepest, largest multi- wavelength surveys in the sky with 2\times10^5 galaxies. It probes the z=1-3 epoch, a key era for studying galaxy evolution, by identifying 7500 LBGs selected as \it GALEX/\nuv-dropouts (1.7<z<2.7), ~7000 BzKs (z=1.5-2.5), and ~2000 narrow-band (NB) emitters (z=1-1.6). However, a complete study of these and other high-z galaxies requires deep NIR imaging, which fully samples their rest-frame optical wavelengths. We propose deep J- and H-band imaging of the SDF with NEWFIRM to identify distant red galaxies (DRGs), z~3 RJL-selected galaxies, and extremely red objects (EROs). We will combine these samples with other high-z galaxies to (\it i) inter-compare DRGs, BzKs, RJLs, LBGs, BXs/BMs, NB emitters, and EROs, which will determine the completeness, selection biases, and total SFRs and stellar mass densities of each of these complementary samplings of the entire galaxy population, (\it ii) break the age-extinction degeneracy in spectral energy distribution modelling of over 20,000 z~1-3 galaxies, (\it iii) study the clustering properties of DRGs and other populations to determine the halo occupation number, and (\it iv) find distant L and T dwarfs in the galactic halo.
