In this paper, the stars and mUltiphase gas in GaLaxiEs (SMUGGLE) model is introduced, which is an explicit and comprehensive stellar feedback model for the moving-mesh code arepo.Abstract:
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. Stellar feedback regulates star formation to the observed level and naturally captures the establishment of a Kennicutt-Schmidt relation. This result is achieved independent of the numerical mass and spatial resolution of the simulations. Gaseous outflows are generated with average mass loading factors of the order of unity. Strong outflow activity is correlated with peaks in the star formation history of the galaxy with evidence that most of the ejected gas eventually rains down onto the disc in a galactic fountain flow that sustains late-time star formation. Finally, the interstellar gas in the galaxy shows a distinct multiphase distribution with a coexistence of cold, warm and hot phases.read more

On the origin of the chemical bimodality of disc stars: a tale of merger and migration
TL;DR: In this article, the authors examined the [Fe/H]-[$\alpha$/Fe] abundance plane in cosmological hydrodynamical simulations of Milky Way like galaxies from the NIHAO-UHD project and showed that the bimodal $\alpha$-sequence is a generic consequence of a gas-rich merger at some time in the Galaxy's evolution.

TL;DR: In this paper, the scaling of outflow mass, momentum, energy, and metal loading factors with galactic disk properties, including star formation rate (SFR) surface density (Sigma_SFR~10-4}-1 M_sun/kpc^2/yr), gas surface density (~1-100 M_Sun/pc 2), and total midplane pressure (or weight) was investigated.
