Description

The CGM of massive galaxies, with stellar masses of 1e10 Msun and higher, has been studied extensively, both theoretically and observationally. The CGM of lower mass galaxies have received less attention, especially from the theoretical side. As a result, many questions remain open - how do the gas and metal budgets of low mass galaxies look like, and what physical processes dominate the CGM in these systems, from non-thermal mechanisms (magnetic fields and cosmic rays), to stellar feedback and galactic outflows. I will present an effort to address these questions with analytic models applied to recent absorption measurements, constraining the gas budget in galaxies with stellar masses below 1e9 Msun. I will also discuss predictions for future observations of these interesting systems, and what we can learn from them.
