The structure and composition of multiphase galactic winds in a Large Magellanic Cloud mass simulated galaxy

Understand

We present the first results from a high resolution simulation with a focus on galactic wind driving for an isolated galaxy with a halo mass of $\sim 10^{11}$ M$_{\odot}$ (similar to the Large Magellanic Cloud) and a total gas mass of $\sim 6 \times 10^{8}$ M$_{\odot}$, resulting in $\sim 10^{8}$ gas cells at $\sim 4$ M$_{\odot}$ mass resolution.

• We adopt a resolved stellar feedback model with non-equilibrium cooling and heating, including photoelectric heating and photo-ionizing radiation, as well as supernovae (SNe), coupled to the second order meshless finite mass (MFM) method for hydrodynamics.
• These features make this the largest resolved-ISM galaxy model run to date.
• We find mean star formation rates around $0.05$ M$_{\odot}$ yr$^{-1}$ and evaluate typical time averaged loading factors for mass ($\eta_\mathrm{M}$ $\sim$ 1.0, in good agreement with recent observations) and energy ($\eta_\mathrm{E}$ $\sim$ 0.01).
