Long-term Optical Variability of Radio-Selected Quasars from the FIRST Survey
David J. Helfand, Remington P. S. Stone, Beth Willman +5
We have obtained single-epoch optical photometry for 201 quasars, taken from the FIRST Bright Quasar Survey, which span a wide range in radio loudness. Comparison with the magnitud…
Keck Hires Observations of the QSO First J104459.6+365605: Evidence for a Large Scale Outflow
Martijn de Kool, Nahum Arav, Robert H. Becker +5
This paper presents an analysis of a Keck HIRES spectrum of the QSO FIRST J104459.6+365605. The line of sight towards the QSO contains two clusters of outflowing clouds that give r…
The Intrinsic Absorber in QSO 2359-1241: Keck and HST Observations
Nahum Arav, Michael S. Brotherton, Robert H. Becker +4
We present detailed analyses of the absorption spectrum seen in QSO 2359-1241 (NVSS J235953-124148). Keck HIRES data reveal absorption from twenty transitions arising from: He I, M…
