EMBER-2: Emulating baryons from dark matter across cosmic time with deep modulation networks
Mauro Bernardini, Robert Feldmann, Jindra Gensior +6
Galaxy formation is a complex problem that connects large scale cosmology with small scale astrophysics over cosmic timescales. Hydrodynamical simulations are the most principled a…
