Simulating the Circumgalactic Medium

Abstract

Electronic Thesis or DissertationWe review the circumgalactic medium and assorted methods of exploring its properties, as well as the methodology of hydrodynamical simulations of galaxies. We evaluate the differences between two specific simulations, IllustrisTNG and FIRE-2. We review the processes involved in creating synthetic spectra from simulations. We compare galaxies from both simulations through the use of simulated spectra from their circumgalactic mediums. We find that the resolution of the simulations has very little effect on the circumgalactic medium, while differences in physical treatments result in disparities between the simulation
