Broad Absorption Line Quasars from the Sloan Digital Sky Survey Second Data Release
Abstract
We present a sample of broad absorption line quasars (BALQSOs) from the Sloan Digital Sky Survey Second Data Release (DR2), scheduled for early 2004. These BALQSOs were selected by an automated algorithm which finds broad absorption troughs by comparing quasars to a set of composite spectra spanning luminosity and emission line FWHM space. We study the properties of BALQSOs identified by both the balnicity index and a new absorption index designed to include troughs with lower outflow velocities and/or velocity widths.
