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.
