Title: The Mass of Systems at 2.5 < z < 5.0

Abstract: We have probed the distribution of Lyman break galaxies
(LBGs) and damped Lyman alpha systems (DLAs) at 2.5 < z < 3.5 via our
narrow-field u'BVRI imaging and spectroscopic survey using the Palomar
COSMIC and Keck LRIS instruments.  I will present the results of this
survey, including the mass of LBGs and interesting implications on the
average mass and nature of DLAs.  I will also introduce our One-Degree
Deep (ODD) wide-field u'BVRIz' imaging and spectroscopic survey using
Subaru SuprimeCam, MMTO Megacam, and Keck DEIMOS instruments to
measure the large-scale distribution of LBGs and DLAs at 3.5 < z <
5.0. By combining the results from both surveys, we will improve the
statistics on the correlation functions and mass of these systems and
search for mass evolution.
