Scientific paper

Building on the already successful Deep Lens Survey (DLS), we propose to extend proposal 09B-0329 and image 8.0 square degrees of southern DLS fields F4 and F5 with NEWFIRM. In seven gray/bright nights we will reach depths of J=23.5 and Ks=22.9(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 seven 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.
