Are red 2MASS QSOs young?
A. Georgakakis, D. L. Clements, G. Bendo +3
We use photometric data from Spitzer to explore the mid- and far-IR properties of 10 red QSOs (J-K>2, R-K>5) selected by combining the 2MASS in the NIR with the SDSS at optical wav…
The Black Hole-Bulge Relationship in QSOs
G. A. Shields, K. Gebhardt, S. Salviander +5
We use QSO emission-line widths to examine the black hole mass - sigma relationship as a function of redshift and to extend the relationship to larger masses. Supermassive black ho…
The PG X-ray QSO sample: Links between the UV-X-ray Continuum and Emission Lines
Beverley J. Wills, M. S. Brotherton, A. Laor +4
The UV to soft X-rays of luminous AGNs dominate their bolometric luminosity, driven by an accretion-powered dynamo at the center. These photons ionize the surrounding gas, thereby…
Hidden Quasars in Ultraluminous Infrared Galaxies
H. D. Tran, M. S. Brotherton, S. A. Stanford +1
Many ultraluminous infrared galaxies (ULIRGs) are powered by quasars hidden in the center, but many are also powered by starbursts. A simply diagnostic diagram is proposed that can…
The Intermediate Line Region and the Baldwin Effect
M. S. Brotherton, Paul J. Francis
Statistical investigations of samples of quasars have established that clusters of properties are correlated. The strongest trends among the ultraviolet emission-line properties ar…
