Title: A Near Infrared View of DLS

Abstract: Building on the already successful Deep Lens Survey (DLS), we propose to image 5.5 square degrees of DLS fields F1 and F2 with NEWFIRM. In five gray/bright nights we will reach depths of J=23.6 and Ks=23.0(AB). The combination of deep optical and NIR data will improve weak lensing mass maps through improved photometric redshifts, identify cool dwarf stars to unprecedented distances extending into the Galactic Halo, and study the high redshift universe with Lyman break galaxies, high redshift radio galaxies, and quasars. The DLS is wider than any survey of equivalent depth, and deeper than any survey of equivalent width. With only five additional nights of NEWFIRM data we can leverage the existing deep optical data to enable new science spanning local Galactic structure to the most distant galaxies in the early universe.
