Neural Network Reconstruction of Non-Gaussian Initial Conditions from Dark Matter Halos
Jelte Bottema, Thomas Flöss, P. Daniel Meerburg
We develop a machine learning approach to reconstructing the cosmological initial conditions from late-time dark matter halo number density fields in redshift space, with the goal…
