Observational constraints on stellar feedback in dwarf galaxies
MLM Collins, JI Read - Nature astronomy, 2022 - nature.com
Feedback to the interstellar medium from ionizing radiation, stellar winds and supernovae is
central to regulating star formation in galaxies. Owing to their low mass (< 109 solar …

INFERNO: Galactic winds in dwarf galaxies with star-by-star simulations including runaway stars
The formation and evolution of galaxies have proved sensitive to the inclusion of stellar
feedback, which is therefore crucial to any successful galaxy model. We present INFERNO …

A comprehensive model for the formation and evolution of the faintest Milky Way dwarf satellites
In this study, we modify the semi-analytic model galacticus in order to accurately reproduce
the observed properties of dwarf galaxies in the Milky Way. We find that reproducing …
