Field-level Comparison and Robustness Analysis of Cosmological N-body Simulations

Field-level Comparison and Robustness Analysis of Cosmological N-body Simulations

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. Unlike previous comparisons focused on summary statistics, we conduct a comprehensive field-level analysis: evaluating...
