The Link Between Halo Gas and Dwarf Galaxy Evolution


September 28, 2023 – 4pm ET / 1pm PT
Mary Putman (Columbia University)

There is a distinct lack of gas-rich/star forming dwarf galaxies within the halos of spiral galaxies. This indicates spiral galaxy halos play an important role in quenching the dwarf satellites. Diffuse gas in the halo is commonly thought to play a role via ram pressure stripping. I will discuss the evidence for dwarf satellite quenching by the circumgalactic medium based on dwarf galaxy observations in the local universe.
