Title: Deep near-infrared imaging of the Extended Groth Strip

Abstract: Galaxies, and the super-massive black holes within them, grew rapidly at 1 < z < 3, when dusty, infrared-luminous starbursts and AGN dominated the energetic output of the universe. Star formation and AGN activity were closely interrelated, and there was abundant AGN activity in ultraluminous infrared galaxies at z ~ 2. The rapid evolution of star formation and AGN activity may have been closely linked with the growth of large-scale structure, leading to a reversal of the SFR-density relation between z ~ 1 and 0. Two new public surveys of the Extended Groth Strip (EGS), FIDEL and AEGISX, are providing the first data suitable for detecting and studying large numbers of IR-luminous galaxies and X-ray AGN at 1 < z < 3 down to faint luminosities, using ultradeep Spitzer far-infrared (70(micron) and 160(mu)m) and Chandra X-ray data over large areas and co-moving volumes. However, redshifts are vitally needed, and spectroscopy from DEEP2 provides little useful information at z > 1. We propose to complete our program of deep NEWFIRM+MOSAIC near-IR+optical imaging of the EGS, a field being studied extensively by a broad user community thanks to its many deep, multiwavelength, public data sets. These data will serve many purposes, and in particular are important for deriving photometric redshifts for large numbers of galaxies at z > 1 including the dusty starbursts and AGN from FIDEL and AEGISX.
