The Statistical Properties of Neutral Gas at z<1.65 from UV Measurements of Damped Lyman Alpha Systems

Understand

We derive the statistical properties of neutral gas at redshifts 0.11<z<1.65 from UV measurements of quasar Lyman alpha absorption lines corresponding to 369 MgII systems with $W^{\lambda2796}_{0} \ge 0.3$ \AA.

• In addition to the 41 damped Lyman alpha (DLA) systems presented in Rao et al.
• (2006), the current DLA sample includes 29 newly discovered DLAs.
• Of these, 26 were found in our HST ACS prism survey for DLAs (Turnshek et al.
