The effect of early stellar feedback and environment on supernovae

Anna McLeod

Feedback from massive stars plays a central role in shaping the evolution of galaxies. Conversely, different galactic environments play a central role in regulating the impact of massive stars. Yet, despite a solid qualitative understanding of feedback, our quantitative knowledge remains poor. Over the last few years, instruments like MUSE, KMOS, and SITELLE have driven true progress in the fields of resolved stellar populations and stellar feedback in nearby galaxies by unlocking spatially resolved studies of orders of magnitude more star-forming regions than previously possible.
I will present recent results of large IFU nearby galaxy surveys, showcasing how these can be used to quantify those stellar feedback mechanisms that act on the ISM before the first supernovae explode, and subsequently, quantify how these mechanisms affect the ISM into which supernovae eventually explode into, as a function of galactic environment. These results offer empirical evidence for the importance of the inclusion of pre-supernova stellar feedback in galaxy evolution simulations.
