The Cosmological Simulation Code OpenGadget3 - Implementation of Self-Interacting Dark Matter

Moritz S. Fischer, Marc Wiertel, Cenanda Arido +7

Dark matter (DM) could be subject to non-gravitational self-interactions which is relevant to resolve potential problems of cold DM on small scales. Their impact on astrophysical o…
