SUMMARY:Supernova clustering and galactic outflows - Matthew Smith (CfA Ha

DESCRIPTION:Galactic outflows are commonly observed in a wide variety of s
 ystems. They form a fundamental component of contemporary theories of gala
 xy formation. This is particularly the case for low-mass galaxies\, where 
 star formation driven outflows are expected to be ubiquitous. They are fre
 quently invoked to regulate stellar mass growth\, reduce the overall baryo
 n fraction\, explain the mass-metallicity scaling relation\, enrich the CG
 M/IGM with metals and possibly transform dark matter density\nprofiles. Ho
 wever\, the mechanisms that launch stellar driven galactic outflows are ve
 ry much an open topic of research. In this talk\, I will examine the sensi
 tivity of galactic wind launching to the clustering properties of supernov
 ae in space and time. In particular\, I will show how the dispersal of sta
 r forming clouds by pre-supernova feedback can modulate the clustering of 
 supernovae\, their ability to form super-bubbles and hence generate galact
 ic outflows. I will do this with the aid of a new state-of-the-art suite o
 f high resolution simulations of dwarf galaxies that links feedback to ind
 ividually resolved massive stars.\n
