A Comparative Study of Isothermal Turbulence Statistics: Fourier Space Driving vs. Point Source Driving
Tejahni Desire, Chang-Goo Kim, Rajsekhar Mohapatra
The turbulence driving parameter (; the ratio of the density to velocity fluctuations) is widely used to infer the dominant mode of…
Pressure-regulated feedback-modulated star formation as a subgrid model for galaxy formation simulations
Sarah M. R. Jeffreson, Eve C. Ostriker, Chang-Goo Kim +1
We present a new subgrid model for interstellar gas evolution in cosmological simulations of galaxy formation, based on the pressure-regulated, feedback-modulated (PRFM) theory of…
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…
Revisiting ram pressure stripping in Wolf-Lundmark-Melotte: No evidence for stripped HI with LGLBS
Daniel R. Rybarczyk, Eric W. Koch, Fabian Caballero Vargas +12
We analyze HI 21-cm observations of the Local Group dwarf galaxy Wolf-Lundmark-Melotte (WLM) from the Local Group L-Band Survey to search for evidence of ram pressure stripping. Wh…
Cosmic Ray Feedback in Galactic Disks: Star Formation, Cosmic Ray Transport, and Multiphase Outflows in TIGRESS++ Simulations
Chang-Goo Kim, Lucia Armillotta, Eve C. Ostriker +5
We present new simulations of local star-forming disks that self-consistently evolve cosmic rays (CRs) and multiphase gas using TIGRESS++. To isolate the role of CRs, we conduct pa…
Prevention is better than cure? Feedback from high specific energy winds in cosmological simulations with Arkenstone
Jake S. Bennett, Matthew C. Smith, Drummond B. Fielding +6
We deploy the new Arkenstone galactic wind model in cosmological simulations for the first time, allowing us to robustly resolve the evolution and impact of high specific energy wi…
