Quasar optical variability and black hole mass
M. Wold, M. S. Brotherton, Z. Shang
In order to investigate the dependence of quasar optical-UV variability on fundamental physical parameters like black hole mass, we have matched quasars from the QUEST1 variability…
The dependence of quasar variability on black hole mass
M. Wold, M. S. Brotherton, Z. Shang
In order to investigate the dependence of quasar variability on fundamental physical parameters like black hole mass, we have matched quasars from the QUEST1 Variability Survey wit…
The PG X-Ray QSO Sample: Links among X-ray, UV & Optical Spectra
Beverley J. Wills, M. S. Brotherton, A. Laor +3
A unique, essentially complete sample of 22 QSOs, with high quality soft X-ray spectra from ROSAT, as well as HST and optical spectrophotometry from below Ly-alpha to above H-alpha…
Spectropolarimetry of FIRST 0840+3633
M. S. Brotherton, Wil van Breugel, Arjun Dey +1
We present Keck spectropolarimetry of a rare ``Iron Lo-BALQSO,'' FIRST 0840+3633. The continuum is 4% polarized near 2000 angstroms rest-frame, but falls to 2% at longer wavelength…
Optical Identification of Quasar 0917+7122 in the Direction of an Extreme-Ultraviolet Source
Dan Maoz, Eran Ofek, Amotz Shemi +6
We report the optical identification of an mag, quasar at the position of a 6 cm radio source and a faint \rosat PSPC X-ray source. The quasar lies within the er…
