Vanishing Absorption and Blueshifted Emission in FeLoBAL Quasars
Alireza Rafiee, Patrik Pirkola, Patrick B. Hall +3
We study the dramatic decrease in iron absorption strength in the iron low-ionization broad absorption line quasar SDSS J084133.15+200525.8. We report on the continued weakening of…
Wide Field Multiband Imaging of Low Redshift Quasar Environments
Jennifer E. Scott, Alireza Rafiee, Jill Bechtold +3
We present photometry of the large scale environments of a sample of twelve broad line AGN with from deep images in the SDSS , , , and filters taken…
The Sloan Digital Sky Survey Stripe 82 Imaging Data: Depth-Optimized Co-adds Over 300 Deg^2 in Five Filters
Linhua Jiang, Xiaohui Fan, Fuyan Bian +9
We present and release co-added images of the Sloan Digital Sky Survey (SDSS) Stripe 82. Stripe 82 covers an area of 300 deg^2 on the Celestial Equator, and has been repeatedly sca…
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…
Supermassive Black Hole Mass Estimates Using Sloan Digital Sky Survey Quasar Spectra at 0.7 < z < 2
Alireza Rafiee, Patrick B. Hall
We present MgII-based black hole mass estimates for 27,602 quasars with rest-frame UV spectra available in the Sloan Digital Sky Survey Data Release Three. This estimation is possi…
Biases in the Quasar Mass-Luminosity Plane
Alireza Rafiee, Patrick B. Hall
We find that the recently reported departure from the Eddington luminosity limit for the highest quasar black hole masses at a given redshift is an artifact due to biases in black…
