Description
A galaxy needs to constantly replenish its HI reservoir in order to continue to form stars over cosmic time. The majority of the baryons in the Universe are in an ionized gas phase outside of a galaxy and therefore must somehow cool and settle on to the galaxy's star forming region. I will discuss the observational evidence for the flow of gas between these two phases.
