Learning the Universe with PRFM-vol: Introducing a new subgrid model for star formation in cosmological simulations
Jan D. Burger, Volker Springel, Eve C. Ostriker +7
We introduce PRFM-vol, a new subgrid model for star formation in cosmological simulations that aims to increase the physical realism of cosmological simulations by leveraging resul…
The GHOSDT Simulations: II. Missing H in Simulations of a Self-Regulated Interstellar Medium
Alon Gurman, Chia-Yu Hu, Michael Y. Grudic +2
Observations in the Galaxy and nearby spirals have established that the HI-to-H transition at solar metallicity occurs at gas weight of $P_{\rm DE}/k_B\approx 10^4 \ \rm K \ cm…
Molecular Hydrogen in High-redshift Damped Lyman-α Absorbers
Alon Gurman, Amiel Sternberg, Shmuel Bialy +2
Simulations predict that circumgalactic hydrogen gas surrounding massive () galaxies at may be predominantly neutral, and c…
The GHOSDT Simulations (Galaxy Hydrodynamical Simulations with Supernova-Driven Turbulence) -- I. Magnetic Support in Gas Rich Disks
Alon Gurman, Ulrich P. Steinwandel, Chia-Yu Hu +1
Galaxies at redshift display high star formation rates (SFRs) with elevated cold gas fractions and column densities. Simulating a self-regulated ISM in a hydrodynamical…
