Broad Absorption Line Quasars in the Early Data Release from the Sloan Digital Sky Survey

Abstract

A new broad absorption line quasar (BAL) sample is derived from the first data released by the Sloan Digital Sky Survey. With 116 objects, it is the largest BAL sample yet assembled. Over the redshift range 1.8 ≤ z ≤ 3.8, the crude fraction with broad absorption in the C IV line is ≃ 15%. This fraction may be subject to small selection-efficiency… (More)
