QSO Host Galaxy Luminosity and [OIII] Line Width as a Surrogate for Stellar Velocity Distribution
E. W. Bonning, G. A. Shields, S. Salviander +1
Supermassive black holes in galactic nuclei show a close relationship between the black hole mass, luminosity, and stellar velocity dispersion (sigma_*) of the host galaxy bulge. P…
How Massive Are BALQSO Winds?
F. Hamann, B. Sabra, V. Junkkarinen +2
We are involved in a program to derive properties of broad absorption line (BAL) winds in quasars using combined UV and X-ray observations. A major obstacle is large uncertainties…
The Puzzle of the Lyman Continuum Polarization of QSOs
Gregory Shields, E. Agol, Omer Blaes
Recent spectropolarimetry of QSOs has revealed a surprising rise in polarization in the Lyman continuum of several objects. We discuss several recent attempts to interpret this fea…
Novae and BAL QSOs: The Aluminum Test
Gregory A. Shields
Novae have been proposed as the explanation of high reported abundances of heavy elements in the gas producing the broad absorption lines (BALs) of QSOs. High abundances of odd num…
