X-ray insights into the nature of PHL 1811 analogs and weak emission-line quasars: Unification with a geometrically thick accretion disk?

X-ray insights into the nature of PHL 1811 analogs and weak emission-line quasars: Unification with a geometrically thick accretion disk?

We present an X-ray and multiwavelength study of 33 weak emission-line quasars (WLQs) and 18 quasars that are analogs of the extreme WLQ, PHL 1811, at z ˜ 0.52.9. New Chandra 1.59.5 ks exploratory observations were obtained for 32 objects while the others have archival X-ray observations. Significan...
