Abstract:We examine to what extent disk and outflow models can reproduce observations of H gas within a few virial radii of galaxies in pairs and groups. Using highly-sensitive HST/COS and FOS spectra of the Q0107 quasar triplet covering Ly𝛼 for z 1, as well as a deep galaxy redshift survey including VIMOS, DEIMOS, GMOS and MUSE data, we test simple disk and outflow models against the H absorption along three lines-of-sight (separated by 200-500 kpc) through nine galaxy groups in this field. These can be compared with… Show more
