Institute for Advanced Study Astrophysics Seminar

ABSTRACT: Many galaxies exhibit the need for a continual source of star formation fuel. Halo gas is a common feature of these galaxies, though utilizing this gas as fuel may require the gas to go through multiple phases. I will discuss new observations and simulations that investigate galaxy gas flows to determine how baryons get into galaxies and metals are mixed throughout their gaseous disks. I will also discuss a population of newly discovered cold clouds that may represent a combination of cooling disk gas, new dwarf galaxies, and stellar feedback.
