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, CUBEP $^{3}$ M, Enzo, Gadget, Gizmo, PKDGrav, and Ramses.…

Learning the Universe: $3 h^{- 1} Gpc$ Tests of a Field Level $N$ -body Simulation Emulator

Matthew T. Scoggins, Matthew Ho, Francisco Villaescusa-Navarro +3

We apply and test a field-level emulator for non-linear cosmic structure formation in a volume matching next-generation surveys. Inferring the cosmological parameters and initial c…
