A comparison of numerical schemes for driven subsonic MHD turbulence
Rüdiger Pakmor, Thomas Guillet, Rebekka Bieri +3
Turbulence is ubiquitous in astrophysical systems, and since most cosmic gas is ionised, it supports magnetic fields. In turbulent environments, these fields are rapidly amplified…
Cosmology with one galaxy: An analytic formula relating with galaxy properties
Kito Liao, Francisco Villaescusa-Navarro, Romain Teyssier +1
Standard cosmological analyses typically treat galaxy formation and cosmological parameter inference as decoupled problems, relying on population-level statistics such as clusterin…
Much Ado About Nothing: Galaxy Formation and Galactic Outflows in Cosmic Voids
Yue Pan, Romain Teyssier, Ulrich P. Steinwandel +1
We present a theoretical framework for calculating the volume filling fraction of galactic outflows in cosmic voids by integrating analytical models for the halo mass function (HMF…
Field-Level Comparison and Robustness Analysis of Cosmological N-body Simulations
Adrian E. Bayer, Francisco Villaescusa-Navarro, Sammy Sharief +6
We present the first field-level comparison of cosmological N-body simulations, considering various widely used codes: Abacus, CUBEPM, Enzo, Gadget, Gizmo, PKDGrav, and Ramses.…
