PHL 1811 Analogs: A Population of X-ray Weak Quasars
17 Jan 2012
Abstract
2012ASPC..460...42W We report on a population of X-ray weak quasars with similar UV emission-line
properties to those of the remarkable quasar PHL 1811. All radio-quiet PHL 1811
analogs are notably X-ray weak by a mean factor of ~13, with hints of heavy
X-ray absorption. Correlations between the X-ray weakness and UV emission-line
properties suggest that PHL 1811 analogs may have extreme wind-dominated broad
emission-line regions (BELRs). We propose an AGN geometry that can potentially
unify the PHL 1811 analogs and the general population of weak-line quasars.
