Simulated Observations of Multiphase Galactic Winds
Abstract
Galactic winds are streams of gas that are often observed flowing at high speed out of star-forming galaxies. Supernova-driven winds are particularly important to model because of their role in regulating the star formation rates and gas supply of galaxies over time. In this study, we are using simulations of multiphase galactic winds modeled with the hydrodynamics code Cholla to create mock observables, such as the optical depth of absorption lines in different ions. The simulations include high density turbulent clouds with a median density of n=0.5 cm^-3 embedded in a low density, hot wind. By comparing our mock observables to observations of the nearest galactic wind systems, we will be able to better constrain theoretical models of the density, velocity, and temperature structure of these winds.
