Column density distribution and cosmological mass density of neutral gas: Sloan Digital Sky Survey-III Data Release 9

Noterdaeme, P., Petitjean, P., Carithers, W. C. et al.

Understand

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 Spectroscopic Survey (BOSS), which is part of the Sloan Digital Sky Survey (SDSS) III.

Our full (non-statistical) sample, based on Data Release 9, comprises 12,081 systems with log N(HI)>=20, out of which 6,839 have log N(HI)>=20.3.
This is the largest DLA sample ever compiled, superseding that from SDSS-II by a factor of seven.
Using a statistical sub-sample and estimating systematics from realistic mock data, we probe the N(HI) distribution at <z> = 2.5.
