Fast Sampling of Cosmological Initial Conditions with Gaussian Neural Posterior Estimation
Oleg Savchenko, Guillermo Franco Abellán, Florian List +2
Knowledge of the primordial matter density field from which the large-scale structure of the Universe emerged over cosmic time is of fundamental importance for cosmology. However,…

Mean-Field Simulation-Based Inference for Cosmological Initial Conditions
Oleg Savchenko, Florian List, Guillermo Franco Abellán +2
Reconstructing cosmological initial conditions (ICs) from late-time observations is a difficult task, which relies on the use of computationally expensive simulators alongside soph…
