Discovery of radio-loud broad absorption line quasars using ultraviolet excess and deep radio selection

We report the discovery of five broad absorption Line (BAL) QSOs in a compl ete sample of 111 ultraviolet excess (UVX) QSO candidates also detected in the NRAO VLA Sky Survey. All five BAL QSOs, which include two high-ionizati on BAL QSOs and three low-ionization BAL QSOs, are formally radio loud. Of QSOs with, z > 0.4, 3% +/- 2% show low-ionization BALs, and of QSOs with z > 1.5, all radio loud, 9% +/- 5% show BALs; these frequencies are consisten t with those of optical surveys. While the first reported radio-loud BAL QS O, FIRST J155633.8+351758, is likely to be heavily dust reddened and thus l ess radio loud than indicated by its observed radio-to-optical luminosity, these QSOs are UVX-selected and probably free of significant dust along the Line of sight. We point out unusual features in two of the BAL QSOs and di scuss the significance finding these heretofore rate objects.
