Figuring Out Gas & Galaxies In Enzo (FOGGIE) XI: Circumgalactic O VI Emission Traces Clumpy Inflowing Recycled Gas
Cassandra Lochhaas, Molly S. Peeples, Brian W. O'Shea +11
The circumgalactic medium (CGM) is host to gas flows into and out of galaxies and regulates galaxy growth, but the multiphase, diffuse gas in this region is challenging to observe.…
Impacts of the Metagalactic Ultraviolet Background on Circumgalactic Medium Absorption Systems
Elias Taira, Claire Kopenhafer, Brian W. Oshea +5
Among the many different pieces of physics that go into simulations of the circumgalactic medium (CGM), the metagalactic ultraviolet background (UVB) plays a significant role in de…
FOGGIE X: Characterizing the Small-Scale Structure of the CGM and its Imprint on Observables
Ramona Augustin, Jason Tumlinson, Molly S. Peeples +11
One of the main unknowns in galaxy evolution is how gas flows into and out of galaxies in the circumgalactic medium (CGM). Studies observing the CGM in absorption using multiple or…
Figuring Out Gas & Galaxies in Enzo (FOGGIE). IX: The Angular Momentum Evolution of Milky Way-like Galaxies and their Circumgalactic Gas
Raymond C. Simons, Molly S. Peeples, Jason Tumlinson +10
We investigate the co-evolution of the angular momentum of Milky Way-like galaxies, their circumgalactic gas, and their dark matter halos using zoom-in simulations from the Figurin…
Figuring Out Gas & Galaxies in Enzo (FOGGIE). II. Emission from the z=3 Circumgalactic Medium
Lauren Corlies, Molly S. Peeples, Jason Tumlinson +4
Observing the circumgalactic medium (CGM) in emission provides 3D maps of the spatial and kinematic extent of the gas that fuels galaxies and receives their feedback. We present mo…
Figuring Out Gas & Galaxies in Enzo (FOGGIE). I. Resolving Simulated Circumgalactic Absorption at 2 < z < 2.5
Molly S. Peeples, Lauren Corlies, Jason Tumlinson +7
We present simulations from the new "Figuring Out Gas & Galaxies in Enzo" (FOGGIE) project. In contrast to most extant simulations of galaxy formation, which concentrate computatio…
