Refueling the Milky Way

Speaker: Scott Lucchini (Harvard CfA) In Person and zoom

As stars form, the gas in galactic disks gets used up. New gas must accrete onto the galaxy to sustain continued star formation. In this talk, I will use simulations to explore some of the possible sources for refueling our Galaxy's star forming material. I will discuss the formation of the Magellanic Stream and how it could impact the Galaxy in the future. I will also compare the observed population of neutral and ionized high-velocity clouds to those found in simulations and further explore their morphologies and accretion rates.
