Simulating the interstellar medium and stellar feedback on a moving mesh: Implementation and isolated galaxies

Understand

We introduce the Stars and MUltiphase Gas in GaLaxiEs -- SMUGGLE model, an explicit and comprehensive stellar feedback model for the moving-mesh code arepo.

• This novel sub-resolution model resolves the multiphase gas structure of the interstellar medium and self-consistently generates gaseous outflows.
• The model implements crucial aspects of stellar feedback including photoionization, radiation pressure, energy and momentum injection from stellar winds and from supernovae.
• We explore this model in high-resolution isolated simulations of Milky Way-like disc galaxies.
