Cosmological implications of baryon acoustic oscillation (BAO) measurements
Éric Aubourg, Stephen Bailey, Julian E. Bautista +90
We derive constraints on cosmological parameters and tests of dark energy models from the combination of baryon acoustic oscillation (BAO) measurements with cosmic microwave backgr…
IGM Constraints from the SDSS-III/BOSS DR9 Ly-alpha Forest Flux Probability Distribution Function
Khee-Gan Lee, Joseph P. Hennawi, David N. Spergel +13
The Ly forest transmission probability distribution function (PDF) is an established probe of the intergalactic medium (IGM) astrophysics, especially the temperature-density rel…
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…
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…
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…
