The Lack of Torus Emission from BL Lacertae Objects: An Infrared View of Unification with WISE
Richard M. Plotkin, Scott F. Anderson, W. N. Brandt +3
We use data from the Wide-Field Infrared Survey Explorer (WISE) to perform a statistical study on the mid-infrared (IR) properties of a large number () of BL Lac objects…
X-ray and Multiwavelength Insights into the Nature of Weak Emission-Line Quasars at Low Redshift
Jianfeng Wu, W. N. Brandt, Scott F. Anderson +5
(Abridged) We report on the X-ray and multiwavelength properties of 11 radio-quiet quasars with weak or no emission lines identified by the Sloan Digital Sky Survey (SDSS) with red…
Can we measure the accretion efficiency of Active Galactic Nuclei?
S. I. Raimundo, A. C. Fabian, R. V. Vasudevan +2
The accretion efficiency for individual black holes is very difficult to determine accurately. There are many factors that can influence each step of the calculation, such as the d…
A Population of X-ray Weak Quasars: PHL 1811 Analogs at High Redshift
Jianfeng Wu, W. N. Brandt, Patrick B. Hall +6
We report the results from Chandra and XMM-Newton observations of a sample of 10 type 1 quasars selected to have unusual UV emission-line properties (weak and blueshifted high-ioni…
