Stellar Feedback and Outflows from Nearby Galaxies

Stellar feedback is one of the largest uncertainties in galaxy formation models today, stemming in part from the need for experimental constraints on the impact of different feedback modes and their dependence on physical parameters. In this talk, I will review studies to measure stellar feedback in star-forming regions in the Milky Way and nearby galaxies. I will show new results from the Physics at High Angular Resolution of Nearby GalaxieS (PHANGS) survey, revealing the multi-phase interstellar medium (ISM) at sub-kpc resolution observed across the electromagnetic spectrum. I will also discuss recent investigations of the hot outflows and cool clouds from starburst-driven galactic winds to explore wind geometry, mass loading, and metal content. I will compare results to predictions from high-resolution simulations to identify missing physics in the models and will discuss the outstanding open questions in the field.
