摘要

We present an absorption line study of the physical and chemical properties of the Leo H i Ring and the Leo I Group as traced by 11 quasar sightlines spread over a approximate to 600 x 800 kpc(2) region. Using HST/COS G130/G160 archival observations as constraints, we couple cloud-by-cloud, multiphase, Bayesian ionization modelling with galaxy property information to determine the plausible origin of the absorbing gas along these sightlines. We search for absorption in the range 600 km s(-1) 更多
