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

Abstract: Galaxies, and the supermassive 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, 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 deep NEWFIRM J+K observations, and the completion of deep optical imaging from program 2007A-0147, to derive photometric redshifts for large numbers of galaxies at z > 1 including the dusty starbursts and AGN from FIDEL and AEGISX.
