X-ray and Multiwavelength Insights into the Inner Structure of High-Luminosity Disc-Like Emitters
B. Luo, W. N. Brandt, M. Eracleous +5
We present X-ray and multiwavelength studies of a sample of eight high-luminosity active galactic nuclei (AGNs) with disc-like Hβemission-line profiles selected from the Sloan Digi…
The Sloan Digital Sky Survey quasar catalog: ninth data release
Isabelle Pâris, Patrick Petitjean, Eric Aubourg +73
We present the Data Release 9 Quasar (DR9Q) catalog from the Baryon Oscillation Spectroscopic Survey (BOSS) of the Sloan Digital Sky Survey III. The catalog includes all BOSS objec…
The Baryon Oscillation Spectroscopic Survey of SDSS-III
Kyle S. Dawson, David J. Schlegel, Christopher P. Ahn +162
The Baryon Oscillation Spectroscopic Survey (BOSS) is designed to measure the scale of baryon acoustic oscillations (BAO) in the clustering of matter over a larger volume than the…
Galaxies with Background QSOs, I: A Search for Strong Galactic H-alpha Lines
Donald G. York, Lorrie A. Straka, Michael Bishof +12
A search for emission lines in foreground galaxies in quasar spectra (z(gal) < z(QSO)) of the Sloan Digital Sky Survey (SDSS) data release 5 (DR5) reveals 23 examples of quasars sh…
The Sloan Digital Sky Survey Quasar Lens Search. V. Final Catalog from the Seventh Data Release
Naohisa Inada, Masamune Oguri, Min-Su Shin +13
We present the final statistical sample of lensed quasars from the Sloan Digital Sky Survey (SDSS) Quasar Lens Search (SQLS). The well-defined statistical lens sample consists of 2…
Monitoring Quasar Colour Variability in Stripe 82
Jesse A. Rogerson, Patrick B. Hall, Chelsea MacLeod +1
Broad Absorption Line (BAL) trough variability is predominantly due to cloud motion transverse to our line of sight. The rate at which the variability occurs indicates the velocity…
