Figuring Out Gas and Galaxies in Enzo

The circumgalactic medium (CGM) is a dynamic, multiphase reservoir of gas regulating the flow of gas between galaxies and intergalactic medium. I will present new results from the FOGGIE (Figuring Out Gas & Galaxies In Enzo) simulation suite, wherein we achieve unprecedented circumgalactic resolution in a cosmological context. With FOGGIE, we are finding that resolving the small-scale structure of the simulated CGM has important ramifications for interpreting and predicting both observable circumgalactic gas and the galaxies themselves. A central tenet of the FOGGIE program is using synthetic data to make predictions for and interpret data from current and future observatories. I will conclude by showing how FOGGIE is uniquely situated for benefiting from the next generation of supercomputers and thus exploring the gas-galaxy connection that observatories of the next several decades will unravel.
