Abstract
Numerical simulations have rapidly progressed to be a powerful accompaniment to observational astronomy. This work describes the modeling of a Milky Way galaxy using one of the latest hydrodynamics codes, Enzo. It is one of the most highly resolved simulations on a global scale and produces a multiphase interstellar medium which, due to its complexity, is normally confined to small scale simulations. We study the formation of stars through gravitational instabilities in the galaxy disk and find good agreement with observations. The addition of feedback supresses star formation and produces a galactic fountain where gas is ejected from the disk's surface and is gravitionally drawn back down.
