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 …

A Self-interacting Dark Matter Solution to the Extreme Diversity of Low-mass Halo Properties

EO Nadler, D Yang, HB Yu - The Astrophysical Journal Letters, 2023 - iopscience.iop.org
The properties of low-mass dark matter (DM) halos appear to be remarkably diverse relative
to cold, collisionless DM predictions, even in the presence of baryons. We show that self …
