Simulating realistic self-interacting dark matter models including small and large-angle scattering
Cenanda Arido, Moritz S. Fischer, Mathias Garny
Dark matter (DM) self-interactions alter the matter distribution on galactic scales and alleviate tensions with observations. A feature of the self-interaction cross section is its…
Dynamical friction from self-interacting dark matter
Moritz S. Fischer, Laura Sagunski
Context. Merging compact objects such as binary black holes provide a promising probe for the physics of dark matter (DM). The gravitational waves emitted during inspiral potential…
Dianoga SIDM: galaxy cluster self-interacting dark matter simulations
Antonio Ragagnin, Massimo Meneghetti, Francesco Calura +5
This work aims at assessing the impact of DM self-interactions on the properties of galaxy clusters. In particular, the goal is to study the angular dependence of the cross section…
Numerical challenges for energy conservation in N-body simulations of collapsing self-interacting dark matter halos
Moritz S. Fischer, Klaus Dolag, Hai-Bo Yu
Dark matter (DM) halos can be subject to gravothermal collapse if the DM is not collisionless, but engaged in strong self-interactions. When the scattering can efficiently transfer…
