This $439,516 National Science Foundation award under the Mathematical and Physical Sciences program (CFDA 47.049) supports a collaborative research project at the University of Washington from September 2022 through August 2025. The project aims to develop a state-of-the-art hydrodynamic galaxy simulation code to study the complex interplay between stellar winds and outflows from star formation with the circumgalactic medium surrounding massive galaxies. Researchers will incorporate a subgrid model into an existing simulation code and validate its accuracy before modeling the circumgalactic medium of Milky Way-like galaxies at the current epoch. They will compare synthetic ultraviolet absorption line spectra from the simulations to Hubble Space Telescope data to advance understanding of the circumgalactic medium's structure and dynamics. Additional simulations are planned to explore how circumgalactic medium structure varies based on galaxy mass and environment. This research has the potential to provide new insights into galaxy evolution processes.
