VizieR Online Data Catalog: The COS CGM Compendium (CCC). II. Lyman limit syst. (Wotta+, 2019)
Abstract
In Paper I (Lehner+, 2018, J/ApJ/866/33), we assembled a sample of 224 HI-selected absorbers with 15<logNHI<19 at z<~1. The data were retrieved from the HST/COS G130M and/or G160M archive with supplementary ground-based observations of MgII and FeII with high-resolution Keck/HIRES and VLT/UVES spectra. An additional 39 absorbers are available from our two first surveys (Lehner+, 2013, J/ApJ/770/138 and Wotta+ 2016ApJ...831...95W). Most of these extra absorbers were observed with HST/STIS, FUSE, and HST/COS G140L. In this paper, we focus solely on the partial Lyman limit systems (pLLSs) and LLSs.
As part of our survey, we acquired new high-resolution observations of MgII (and FeII; see Paper I) for 113 absorbers. Data for three of these absorbers were also initially obtained with low-resolution spectra (R~4000). (3 data files).- Publication:
