Variation in the Scattering Shroud Surrounding Markarian 231
S. C. Gallagher, Gary D. Schmidt, Paul S. Smith +5
We present a detailed study of the nuclear structure of the highly polarized broad absorption line quasar, Mrk 231, through a multiwavelength campaign of Chandra observations, opti…
XMM-NEWTON Reveals the Quasar Outflow in PG 1115+080
G. Chartas, W. N. Brandt, S. C. Gallagher
We report on an observation of the Broad Absorption Line (BAL) quasar PG 1115+080 performed with the XMM-Newton observatory. Spectral analysis reveals the second case of a relativi…
The Chandra Deep Field-North Survey. XIV. X-ray detected Obscured AGNs and Starburst Galaxies in the Bright Submm Source Population
D. M. Alexander, F. E. Bauer, W. N. Brandt +6
We provide X-ray constraints and perform the first X-ray spectral analyses for bright (f_850>=5mJy; S/N>=4) SCUBA sources in an 8.4'x8.4' area of the 2 Ms Chandra Deep Field-North…
Chandra Detects Relativistic Broad Absorption Lines from APM 08279+5255
G. Chartas, W. N. Brandt, S. C. Gallagher +1
We report the discovery of X-ray broad absorption lines (BALs) from the BALQSO APM 08279+5255 originating from material moving at relativistic velocities with respect to the centra…
X-ray Spectroscopy of BAL and Mini-BAL QSOs
S. C. Gallagher, W. N. Brandt, G. Chartas +1
BAL QSOs are notoriously faint X-ray sources, presumably due to extreme intrinsic absorption. However, several objects have begun to appear through the obscuration with recent X-ra…
Observational Similarities and Potential Connections Between Luminous Ultrasoft NLS1s and BALQSOs
W. N. Brandt, S. C. Gallagher
Luminous ultrasoft NLS1s and low-ionization BALQSOs share many properties, and they both represent important extremes of the active galaxy phenomenon. We briefly discuss their obse…
