The Diffuse Gas in Cosmic Ecosystems Science Interest Group (DGCE SIG) provides a forum for researchers and students who are interested in diffuse gas throughout the universe, in the interstellar, circum-galactic, circum-quasar, and intergalactic media, to come together to discuss the latest discoveries and ideas. Information about the upcoming seminar is given below. More information about the scientific topics of the Diffuse Gas in Cosmic Ecosystems SIG can be found on their landing page.

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.
