Abstract:
We present a study of the column density distribution and cosmological
mass density of neutral gas from a survey of Damped Lyman-alpha
systems in the Sloan Digital Sky Survey III Data Release 9.
Description:
Our sample of high redshift Damped Lyman-alpha systems (DLAs) and
sub-DLAs is presented along with associated metal equivalent widths
and/or upper-limits.
