PKS 1004+13: A high-inclination highly absorbed radio-loud QSO-the first radio-loud broad absorption line QSO at low redshift?

The existence of broad absorption line (BAL) outflows in only radio-quiet Q SOs was thought to be an important clue to mass ejection and the radio-loud -radio-quiet dichotomy. Recently, a few radio-loud BAL QSOs have been disco vered at high redshift. We present evidence that PKS 1004+13 is a radio-lou d BAL QSO. It would be the first known at low redshift (z(em) = 0.24) and o ne of the most radio-luminous. For PKS 1004+13, there appear to be broad ab sorption troughs of O VI, N V, Si IV, and C IV, indicating high-ionization outflows up to similar to 10,000 km s(-1). There are also two strong, broad (similar to 550 km s(-1)), high-ionization associated absorption systems t hat show partial covering of the continuum source. The strong UV absorption we have detected suggests that the extreme, soft X-ray weakness of PKS 100 4+13 is primarily the result of absorption. The large radio-lobe dominance indicates BAL and associated gas at high inclinations to the central engine axis, perhaps in a line of sight that passes through an accretion disk win d.
