We will present preliminary results on SDSS optical quasars with radio counterparts in the VLA-FIRST survey catalog. Of particular interest is a sample of radio-detected Broad Absorption Line (BAL) quasars which, contrary to previous claims, are found to be mostly radio-intermediate to radio-loud objects. The red nature of the continuum emission of BAL quasars is confirmed by SDSS.
The Sloan Digital Sky Survey (SDSS) is a joint project of The University of Chicago, Fermilab, the Institute for Advanced Study, the Japan Participation Group, The Johns Hopkins University, the Max-Planck-Institute for Astronomy, New Mexico State University, Princeton University, the United States Naval Observatory, and the University of Washington. Apache Point Observatory, site of the SDSS telescopes, is operated by the Astrophysical Research Consortium (ARC). Funding for the project has been provided by the Alfred P. Sloan Foundation, the SDSS member institutions, the National Aeronautics and Space Administration, the National Science Foundation, the U.S. Department of Energy, Monbusho, and the Max Planck Society.
