Getting at the fundamental properties of damped Lyman alpha systems (DLAs)

I have conducted two large imaging and spectroscopic surveys for high redshift (z = 2 - 5) LBGs and damped Lyman alpha systems (DLAs). These surveys exploit the sensitivity and field-of-view of the Keck LRIS and DEIMOS, Palomar COSMIC, MMT MegaCam, and Subaru SuprimeCam instruments (Cooke et al. 2005, 2011c in prep.). A primary goal of these surveys is to measure the 3-D distribution of LBGs and DLAs at z ~ 3 and z ~ 4 via the spatial correlation and cross-correlation functions. The measurements from these surveys help determine fundamental properties such as galaxy bias, mass, luminosity, and evolutionary paths. The first measurement of the mass of z ~ 3 DLAs is presented in (Cooke et al. 2006a, 2006b). The larger, wide-field z = 2 - 5 survey will improve the statistics and probe extended sightlines via bright LBGs to provide, for the first time, the geometry of DLAs at high redshift.
