Field-Level Inference of Primordial Non-Gaussianity with the Quijote Simulation Suite

Adam Andrews, Jens Jasche, Guilhem Lavaux +10

Local primordial non-Gaussianity, parameterised as $f_{NL}^{local}$ , will be stringently constrained using state-of-the-art methods applied to next-generation galaxy redshi…

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…

Bayesian Inference of Initial Conditions from Non-Linear Cosmic Structures using Field-Level Emulators

Ludvig Doeser, Drew Jamieson, Stephen Stopyra +3

Analysing next-generation cosmological data requires balancing accurate modeling of non-linear gravitational structure formation and computational demands. We propose a solution by…
