The BOSS Lyman-alpha Forest Sample from SDSS Data Release 9
Khee-Gan Lee, Stephen Bailey, Leslie E. Bartsch +50
We present the BOSS Lyman-alpha (Lya) Forest Sample from SDSS Data Release 9, comprising 54,468 quasar spectra with zqso > 2.15 suitable for Lya forest analysis. This data set prob…
Baryon Acoustic Oscillations in the Ly-α forest of BOSS quasars
Nicolás G. Busca, Timothée Delubac, James Rich +59
We report a detection of the baryon acoustic oscillation (BAO) feature in the three-dimensional correlation function of the transmitted flux fraction in the \Lya forest of high-red…
The SDSS-III Baryon Oscillation Spectroscopic Survey: The Quasar Luminosity Function from Data Release Nine
Nicholas P. Ross, Ian D. McGreer, Martin White +39
We present a new measurement of the optical Quasar Luminosity Function (QLF), using data from the Sloan Digital Sky Survey-III: Baryon Oscillation Spectroscopic Survey (SDSS-III: B…
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…
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…
Sample variance and Lyman-alpha forest transmission statistics
Emmanuel Rollinde, Tom Theuns, Joop Schaye +2
We compare the observed probability distribution function of the transmission in the \HI\ Lyman-alpha forest, measured from the UVES 'Large Programme' sample at redshifts z=[2,2.5,…
