| I will present new results from an UV absorption-line survey of the outer-group medium (OGrM) in nearby galaxy groups based on HST/COS data. Analyzing coherent absorption patterns of HI and high metal ions, our survey allows us to characterize the extent, physical conditions and total mass of the OGrM and its connection to the cosmic web at 2-3 (group) virial radii. In this talk, I will discuss the relevance of these findings for our understanding of the gas distribution in groups and its connection to the circumgalactic medium of group member galaxies. |
