Molly Peeples: The circumgalactic medium (CGM) is a dynamic, multiphase reservoir of gas regulating the flow of gas between galaxies and intergalactic medium. Yet, these critical gas flows are generically under-resolved in cosmological hydrodynamic simulations of galaxy evolution. I will present new results from our FOGGIE (Figuring Out Gas & Galaxies In Enzo) simulation suite, wherein we achieve unprecedented circumgalactic resolution in a cosmological context. I will show that resolving the small-scale structure of the simulated CGM has important ramifications for interpreting and predicting observable circumgalactic gas.
