Characterizing the WISE-selected Heavily Obscured Quasar Population with Optical Spectroscopy from the Southern African Large Telescope
R. E. Hviding, R. C. Hickox, K. N. Hainline +4
We present the results of an optical spectroscopic survey of 46 heavily obscured quasar candidates. Objects are selected using their mid-infrared (mid-IR) colours and magnitudes fr…
Composite Spectral Energy Distributions and Infrared-Optical Colors of Type 1 and Type 2 Quasars
Ryan C. Hickox, Adam D. Myers, Jenny E. Greene +3
We present observed mid-infrared and optical colors and composite spectral energy distributions (SEDs) of type 1 (broad-line) and 2 (narrow-line) quasars selected from Sloan Digita…
Do you see what I see? Exploring the consequences of luminosity limits in black hole-galaxy evolution studies
Mackenzie L. Jones, Ryan C. Hickox, Simon J. Mutch +3
In studies of the connection between active galactic nuclei (AGN) and their host galaxies there is widespread disagreement on some key aspects stemming largely from a lack of under…
The characteristic halo masses of half-a-million WISE-selected quasars
Michael A. DiPompeo, Ryan C. Hickox, Sarah Eftekharzadeh +1
Recent work has found evidence for a difference in the bias and dark matter halo masses of WISE-selected obscured and unobscured quasars, implying a distinction between these popul…
The Impact of the Dusty Torus on Obscured Quasar Halo Mass Measurements
Michael A. DiPompeo, Jessie C. Runnoe, Ryan C. Hickox +2
Recent studies have found that obscured quasars cluster more strongly and are thus hosted by dark matter haloes of larger mass than their unobscured counterparts. These results pos…
Bias in C IV-based quasar black hole mass scaling relationships from reverberation mapped samples
Michael S. Brotherton, J. C. Runnoe, Zhaohui Shang +1
The masses of the black holes powering quasars represent a fundamental parameter of active galaxies. Estimates of quasar black hole masses using single-epoch spectra are quite unce…
