The Frequency and Radio Properties of Broad Absorption Line Quasars

Abstract

A sample of 67 broad absorption line quasars (BALQSOs) from the Large Bright Quasar Survey (LBQS) is used to estimate the observed and intrinsic fraction of BAL quasars in optically selected samples at intermediate (BJ~=18.5) magnitudes. The observed BALQSO fraction in the redshift range 1.5 ~1 mJy radio sources. Observations reported here were obtained in part at the MMT Observatory, a joint facility of the Smithsonian Institution and the University of Arizona.
