• Damped Lyα Systems at z < 1.65: The Expanded Sloan Digital Sky Survey Hubble Space Telescope Sample (2006, background): “Ledoux et al. (2003) find that the DLAs in which H2 is detected have among the highest metallicities and the highest depletion factors, hinting at the possibility of much higher depletions in much higher column density molecular gas clouds.”
• Velocity-metallicity correlation for high-z DLA galaxies: evidence of a mass-metallicity relation? (2006, methodology): “Most of the systems in our sample were selected from the follow-up of the Large Bright QSO Survey (LBQS; Wolfe et al. 1995) and observed at the ESO VLT with UVES between 2000 and 2004 in the course of a systematic search for molecular hydrogen atzabs> 1.8 (Petitjean et al. 2000; Ledoux et al. 2003).”
• The ESO UVES advanced data products quasar sample: II. Cosmological evolution of the neutral gas mass density (2013, background): “The redshift path and an additional sub-DLA reported by Ledoux et al. (2003) were included in our statistical sample.”
• Evolution of the cosmological mass density of neutral gas from Sloan Digital Sky Survey II - Data Release 7 (2009, background): “In addition, there is only a small tendency for increasing H2 molecular fraction with larger Hi column density (Ledoux et al. 2003; Noterdaeme et al. 2008a).”
• Damped Lyman α systems in galaxy formation simulations (2008, background): “On the other hand, observations suggest that DLAs harbour very little molecular gas, with fractions at the very mostfH2 ∼ 10 −2 (Ledoux et al. 2003).”
• First detection of CO in a high-redshift damped Lyman-α system (2008, background): “We noticed a strong preference for H2-bearing DLAs being associated with C i absorption (Srianand et al. 2005) and having high metallicities and large depletion factors (Petitjean et al. 2006; Noterdaeme et al. 2008).”
