[40.15] Identifying Moderate Redshift Damped Lyman-alpha Galaxies

L.J. Storrie-Lombardi, M. Lacy (SIRTF Science Center ), R.H. Becker (IGPP/LLNL, U.C. Davis)

We present here preliminary results from a survey of quasar fields with damped Lyman\alpha absorption systems (DLA) in the redshift range 0.6 < z < 2. This is a program to identify new DLA absorbers with z < 2 and understand the nature of the galaxies responsible for the absorption and their contribution to the comoving mass density in neutral gas at moderate redshifts. NIRC K' imaging is combined with LRIS spectroscopy of the candidate galaxies detected in the field and an HST program to identify the Lyman-alpha absorption based on the strength of MgII seen in the optical quasar spectra.
