[77.06] The View Through the Wind: Broad Absorption Line QSOs with Chandra

S.C. Gallagher (Penn State)

Broad Absorption Line QSOs are notoriously faint X-ray sources, and we are just beginning to accumulate data with enough counts for spectral analysis. From our observations, general patterns are emerging: the X-ray continua are typical of normal QSOs, and the signatures of a significant column density of complex absorbing gas are clear. To elucidate the characteristics of the population as a whole, we are conducting a survey of a well-defined sample of 18 BAL QSOs from the Large Bright Quasar Survey with the Chandra ACIS-S3 instrument. The low background and excellent spatial resolution of Chandra permit sensitive observations in a relatively short time. With the Chandra data and optical spectroscopic follow-up with the Hobby-Eberly Telescope, we compare the X-ray properties of the BAL QSOs with their UV absorption-line characteristics.
