Broad Absorption Line Quasars from the SDSS DR3

Pat Hall (York)

I review and discuss SDSS results on BAL quasars, including preliminary results from a new catalog of over a thousand Broad Absorption Line quasars from the SDSS Data Release 3. These BAL quasars were automatically identified using criteria less restrictive than the traditional balnicity index. Parameters such as absorption width, depth and maximum velocity were measured for each trough, and some interesting trends of absorption properties with quasar properties such as luminosity are found.
