The Dependence of C IV Broad Absorption Line Properties on Accompanying Si IV and Al III Absorption: Relating Quasar-Wind Ionization Levels, Kinematics, and Column Densities
N. Filiz Ak, W. N. Brandt, P. B. Hall +10
We consider how the profile and multi-year variability properties of a large sample of C IV Broad Absorption Line (BAL) troughs change when BALs from Si IV and/or Al III are presen…
Baryon Acoustic Oscillations in the Lyα forest of BOSS DR11 quasars
Timothée Delubac, Julian E. Bautista, Nicolás G. Busca +35
We report a detection of the baryon acoustic oscillation (BAO) feature in the flux-correlation function of the Lyα forest of high-redshift quasars with a statistical significance o…
Broad Absorption Line Variability on Multi-Year Timescales in a Large Quasar Sample
N. Filiz Ak, W. N. Brandt, P. B. Hall +10
We present a detailed investigation of the variability of 428 C IV and 235 Si IV Broad Absorption Line (BAL) troughs identified in multi-epoch observations of 291 quasars by the Sl…
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…
The clustering of galaxies in the SDSS-III Baryon Oscillation Spectroscopic Survey: weighing the neutrino mass using the galaxy power spectrum of the CMASS sample
Gong-Bo Zhao, Shun Saito, Will J. Percival +15
We measure the sum of the neutrino particle masses using the three-dimensional galaxy power spectrum of the SDSS-III Baryon Oscillation Spectroscopic Survey (BOSS) Data Release 9 (…
Column density distribution and cosmological mass density of neutral gas: Sloan Digital Sky Survey-III Data Release 9
P. Noterdaeme, P. Petitjean, W. C. Carithers +19
We present the first results from an ongoing survey for Damped Lyman-alpha systems (DLAs) in the spectra of z>2 quasars observed in the course of the Baryon Oscillation Spectroscop…
