Consequences of Dust in Damped Lyman-Alpha Systemstion of Cr relative to Zn. Both methods give a typical dust-to-gas ratio roughly 10% of that in the Milky Way. Here, we review some of the consequences of these observations. First, the dust in damped Ly. systems causes obscuration and hence incompleteness in optically selected samples of quasars. W

The Mass Spectrum of Giant Hydrogen Clouds Associated with Damped Ly, Absorberswn and nearby galaxies shows that these absorbers may be interpreted as giant hydrogen clouds (GHCs) in intervening galaxies along the lines-of-sight. We show that the observational data on the redshift and column density distribution of the DLAs may be used to study the mass spectrum of GHCs and it

A Damped Ly, Survey at , < 1.65damped Ly. systems studied so far are found to have corresponding MgII absorption. From known MgII absorption-line statistics, we determine an upper limit to the number of damped Ly. systems per unit redshift, ..., at <.> ≈ 0.8 that is consistent with the trend at higher redshift as well as the numb
