The z=0.54 LoBAL Quasar SDSS J085053.12+445122.5: II. The Nature of Partial Covering in the Broad-Absorption-Line Outflow
Karen M. Leighly, Donald M. Terndrup, Adrian B. Lucy +5
It has been known for 20 years that the absorbing gas in broad absorption line quasars does not completely cover the continuum emission region, and that partial covering must be ac…
The Sloan Digital Sky Survey Reverberation Mapping Project: Sample Characterization
Yue Shen, Patrick B. Hall, Keith Horne +24
We present a detailed characterization of the 849 broad-line quasars from the Sloan Digital Sky Survey Reverberation Mapping (SDSS-RM) project. Our quasar sample covers a redshift…
The z=0.54 LoBAL Quasar SDSS J085053.12+445122.5: I. Spectral Synthesis Analysis Reveals a Massive Outflow
Karen M. Leighly, Donald M. Terndrup, Sarah C. Gallagher +2
We introduce SimBAL, a novel spectral-synthesis procedure that uses large grids of ionic column densities generated by the photoionization code Cloudy and a Bayesian model calibrat…
Connecting the X-ray properties of weak-line and typical quasars: testing for a geometrically thick accretion disk
Qingling Ni, W. N. Brandt, B. Luo +8
We present X-ray and multiwavelength analyses of 32 weak emission-line quasars (WLQs) selected in a consistent and unbiased manner. New 3.1-4.8 ks observations were obtai…
Winds as the origin of radio emission in radio-quiet extremely red quasars
Hsiang-Chih Hwang, Nadia L. Zakamska, Rachael M. Alexandroff +4
Most active galactic nuclei (AGNs) are radio-quiet, and the origin of their radio emission is not well-understood. One hypothesis is that this radio emission is a by-product of qua…
The Sloan Digital Sky Survey Reverberation Mapping Project: the CIV Blueshift, Its Variability, and Its Dependence Upon Quasar Properties
Mouyuan Sun, Yongquan Xue, Gordon T. Richards +4
We use the multi-epoch spectra of 362 quasars from the Sloan Digital Sky Survey Reverberation Mapping project to investigate the dependence of the blueshift of CIV relative to MgII…
