Illuminating the Circumgalactic Medium Colin Hill, Nick Battaglia, and Matt McQuinn

The next decade of mm-wave observations will transform our understanding of galaxy formation, driven by precisely measuring the thermodynamic properties of ionized gas, using the cosmic microwave background as a "backlight". In this session we will discuss how these observations will probe the CGM gas well into the outskirts of hitherto-unexplored high-redshift, low-mass systems and the synergies with other observables.

Chair/Moderator: Nick Battaglia

Note Taker: Colin Hill
