Diffuse Gas in Cosmic Ecosystems
Science Interest Group


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. This SIG will host monthly topical talks by experts on diffuse gas and its properties, along with regular discussion on what observations and instruments are needed to move the field forward. The talk schedule is monthly, on the 4th Thursday of the month at 4pm Eastern/1pm Pacific time.

DGCE SIG motivation: Most of the ordinary matter in the universe is found in the tenuous gas between stars and galaxies. This matter is mostly diffuse and found in a mixture of phases, spanning a huge range of size scales, connecting galaxies to each other in a massive cosmic web, while also playing a key role in star and planet formation. The physical processes that govern the behavior of this material are the same, regardless of the scale. This Science Interest Group (SIG) organizes community input on Diffuse Gas found across Cosmic Ecosystems, emphasizing the interconnectedness of the systems at all scales. The SIG focus includes the circumgalactic and intergalactic media, and the interstellar medium environment of gas/diffuse plasma between stars and galaxies, as well as the flows within and around each of these media as they connect to each other. This SIG enhances the voice of this critical field within the broader astronomical community.

The next DGCE SIG seminar is on May 25, 2023. »  Details
