QSO 2359-1241: A bright, highly polarized, radio-moderate, reddened, low-ionization broad absorption line quasar

We report the discovery of a bright quasar (E = 15.8, z = 0.868) associated with the flat-spectrum radio source NVSS J235953 - 124148. This quasar, which we designate QSO 2359 - 1241, possesses a rare combination of extreme properties that make it of special interest. These properties include intrinsic high-velocity outflow seen in absorption for both high- and low-ionization species, high optical polarization (similar to5%), significant radio emission, and dust reddening. The dereddened absolute magnitude of QSO 2359 - 1241 places it among the three most optically luminous quasars known at z < 1. High-resolution spectroscopy and a detailed analysis of the optical/ultraviolet absorption features will be given in a companion paper.
