We present the first results from an ongoing survey for damped Lyman-α 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 6839 have logN(Hi) ≥ 20.3. This is the largest DLA sample ever compiled, superseding that from SDSS-II by a factor of seven.

The Neutral Hydrogen Cosmological Mass Density at z = 5 (2015, methodology): “4.4 DLA incidence rate and differential NHI distribution Figure 8 shows the differential NHI distribution from the GGG sample compared to that from the SDSS sample from Prochaska & Wolfe (2009), which is consistent with the more recent estimate from Noterdaeme et al. 2012.”

Evolution of the atomic and molecular gas content of galaxies (2013, methodology): “…of the global atomic gas content of the Universe (Ωgas) at much higher redshifts (z < 4.5; e.g., Rao, Turnshek & Nestor 2006; Prochaska & Wolfe 2009; Noterdaeme et al. 2012), but the exact nature of these systems, and their connection to galaxies detected in emission, is still unclear, making the…”
THE SDSS-IV EXTENDED BARYON OSCILLATION SPECTROSCOPIC SURVEY: QUASAR TARGET SELECTION (2015, methodology): “…analyses of the Lyman-α Forest with BOSS have provided substantial new insights into cosmological constraints (e.g. Slosar et al. 2011, 2013; Noterdaeme et al. 2012; Busca et al. 2013; Kirkby et al. 2013; Palanque-Delabrouille et al. 2013b; Font-Ribera et al. 2014; Delubac et al. 2015).…”

The ESO UVES advanced data products quasar sample: II. Cosmological evolution of the neutral gas mass density (2013, methodology): “There is a deficit of logNH I > 21.7 DLAs in the Péroux et al. (2003b) sample because their redshift path is smaller than that of the SDSS surveys (Noterdaeme et al. 2009, 2012), the latter providing a better estimation offH I(N, z) down to logNH I & 22.”
