Filippo Fraternali - October 31, 2014 Mining the corona of the Milky Way The Milky Way and other disk galaxies need continuous gas accretion in order to feed their star formation. The likely source of this accretion is the low-density and high-temperature corona that surrounds the Galaxy and contains a significant fraction of the missing baryons. To date the characterisation of this corona has not reached a consensus and its density and total mass remain uncertain. In the first part of my talk, I describe a new way to determine the properties of the Milky Way corona using gas stripping from dwarf satellites. The result is that the corona must contain at least as many baryons as the Galactic disk. In the second part, I discuss the theoretical expectations for the cooling and accretion of the corona and the effect of supernova feedback in driving this accretion
