DGCE SIG Seminar, 27 Aug 2026
Open Questions in Galactic Wind Physics and Phenomenology. Speaker: Todd Thompson, Professor and Department Chair, Ohio State University The post DGCE SIG Seminar, 27 Aug 2026 appeared first on NASA Science .
On the 27th of August 2026, the DGCE SIG Seminar took place, focusing on the study of diffuse gas in cosmic ecosystems. The seminar was held virtually, with Todd Thompson, a Professor and Chair of the Department at Ohio State University, as the speaker. His presentation centered around two key ideas: the potential precipitation of cool gas from a galaxy's super-heated hot phase and the direct acceleration of cool gas from the galaxy through momentum injection.
Thompson emphasized the challenges and open questions surrounding these concepts, both in terms of observational and theoretical aspects. His talk aimed to connect the physical scales, from molecular clouds to the near-galactic medium and the circumgalactic medium, to observational constraints. The seminar was part of the Cosmic Origins Community, which is one of the Science Groups within the Executive Committee.
To stay updated on future seminars and other DGCE SIG events, attendees were encouraged to subscribe to the community email news list. The seminar provided a platform for discussing the complex dynamics of galactic winds and the uncertainties surrounding the physics of cool and cold outflowing high velocity gas in rapidly star-forming galaxies.
