Serendipitous Discovery of a BAL QSO at z = 2.169
Abstract
We report the serendipitous discovery of a BAL QSO at z = 2.169, located 41'' southwest of 3C 48. We present Keck LRIS spectroscopy covering rest frame 1500 A to 2300 A . The C IV BAL has three components and it extends to outflow velocities of at least 12,000 km/s. The BAL QSO has an intervening low-ionization metal-line absorption system at z = 1.667 which is likely to be a damped Ly-alpha absorber. HST images show extended luminous material around the QSO, which could be either the host galaxy or the intervening system.
