SUMMARY:CRAL@ENS Seminar - Stefanie Walch-Gassner (University of Cologne)
DESCRIPTION:The impact of stellar feedback on galaxies\nSmall-scale stellar feedback can impact the large-scale evolution of galaxies by regulating star formation and by driving galactic fountain flows and outflows. Using modern high-performance computing simulations\, we can study the relative importance of stellar winds\, radiation\, and supernovae in shaping the multi-phase interstellar medium. Using these simulations\, we find that pre-supernova feedback is highly relevant for regulating star formation. In particular\, the ionizing radiation of massive stars is dominating over the impact of non-ionizing radiation or stellar winds. On the other hand\, supernovae drive hot bubbles and super-bubbles with substantially higher pressure than the typical midplane pressure of a disk galaxy\, thereby pushing gas out into the circum-galactic medium. Additionally\, cosmic rays\, which are in this context most importantly accelerated by supernova shocks\, help to sustain the galactic outflow via a vertical cosmic ray pressure gradient.
