Field-level Neural Network Emulator for Cosmological N-body Simulations
We build a field-level emulator for cosmic structure formation that is accurate in the nonlinear regime. Our emulator consists of two convolutional neural networks trained to output the nonlinear displacements and velocities of N -body simulation particles based on their linear inputs. Cosmology dep...
