FOGGIE: Figuring Out Gas & Galaxies In Enzo XII. The Formation and Evolution of Extended HI Galactic Disks and Warps with a Dynamic Circumgalactic medium
Cameron W. Trapp, Molly S. Peeples, Jason Tumlinson +8
Atomic hydrogen (HI) is an important component of gas in and around galaxies and forms extended disk-like structures well beyond the extent of starlight. Here we investigate the pr…

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) VIII: Complex and Stochastic Metallicity Gradients at z > 2
Ayan Acharyya, Molly S. Peeples, Jason Tumlinson +7
Gas-phase metallicity gradients are a crucial element in understanding the chemical evolution of galaxies. We use the FOGGIE simulations to study the metallicity gradients ($\nabla…
