X-ray Insights into the Nature of PHL 1811 Analogs and Weak Emission-Line Quasars: Unification with a Geometrically Thick Accretion Disk?
B. Luo, W. N. Brandt, P. B. Hall +9
We present an X-ray and multiwavelength study of 33 weak emission-line quasars (WLQs) and 18 quasars that are analogs of the extreme WLQ, PHL 1811, at z ~ 0.5-2.9. New Chandra 1.5-…
Broad Absorption Line Variability in Radio-Loud Quasars
C. A. Welling, B. P. Miller, W. N. Brandt +2
We investigate C IV broad absorption line (BAL) variability within a sample of 46 radio-loud quasars (RLQs), selected from SDSS/FIRST data to include both core-dominated (39) and l…
Exploratory X-ray Monitoring of Luminous Radio-Quiet Quasars at High Redshift: Initial Results
Ohad Shemmer, W. N. Brandt, Maurizio Paolillo +6
We present initial results from an exploratory X-ray monitoring project of two groups of comparably luminous radio-quiet quasars (RQQs). The first consists of four sources at 4.10…
Variability-based AGN selection using image subtraction in the SDSS and LSST era
Yumi Choi, Robert R. Gibson, Andrew C. Becker +5
With upcoming all sky surveys such as LSST poised to generate a deep digital movie of the optical sky, variability-based AGN selection will enable the construction of highly-comple…
Broad Absorption Line Quasars with Redshifted Troughs: High-Velocity Infall or Rotationally Dominated Outflows?
Patrick B. Hall, W. N. Brandt, P. Petitjean +19
We report the discovery in the Sloan Digital Sky Survey and the SDSS-III Baryon Oscillation Spectroscopic Survey of seventeen broad absorption line (BAL) quasars with high-ionizati…
Effect of Measurement Errors on Predicted Cosmological Constraints from Shear Peak Statistics with LSST
D. Bard, J. M. Kratochvil, C. Chang +26
The statistics of peak counts in reconstructed shear maps contain information beyond the power spectrum, and can improve cosmological constraints from measurements of the power spe…
