VizieR Online Data Catalog: Ions density in the CGM of low mass galaxy groups (Pointon+, 2020)

In order to study the circumgalactic medium (CGM) of the group environments, we use the "Multiphase Galaxy Halos" Survey, which is comprised of UV Hubble Space Telescope/Cosmic Origins Spectrograph (HST/COS) spectra from our program (PID 13398), as well as data taken from the literature (Chen+, 2001, J/ApJ/559/654; Chen & Mulchaey, 2009, J/ApJ/701/1219; Meiring+, 2011ApJ...732...35M; Werk+, 2012ApJS..198....3W; Johnson+, 2013, J/MNRAS/434/1765). All quasars in the sample have COS UV spectra (R~20000), while two also have reduced UV spectra from the Far-Ultraviolet Spectroscopic Explorer (FUSE) telescope (R~30000).

Eight quasars have optical spectra from High Resolution Echelle Spectrometer (Keck/HIRES) and Very Large Telscope/Ultraviolet and Visual Echelle Spectrograph (VLT/UVES) with a resolving power of R~40000.
