MARVELously Dark: the density profile evolution of dwarf halos in velocity-dependent SIDM
Anna Engelhardt, Ferah Munshi, Annika H. G. Peter +6
Self-interacting dark matter (SIDM) with a sufficiently large cross section has been shown to naturally produce constant dark matter (DM) cores, as well as core-collapse, at the ce…
Till the core collapses: the evolution and properties of self-interacting dark matter subhalos
Zhichao Carton Zeng, Annika H. G. Peter, Xiaolong Du +6
One of the hottest questions in the cosmology of self-interacting dark matter (SIDM) is whether scatterings can induce detectable core-collapse in halos by the present day. Because…
Calibrating the SIDM Gravothermal Catastrophe with N-body Simulations
Charlie Mace, Shengqi Yang, Zhichao Carton Zeng +3
Self-interacting dark matter (SIDM) theories predict that dark matter halos experience core-collapse in late-stage evolution, a process where the halo's inner region rapidly increa…
Convergence Tests of Self-Interacting Dark Matter Simulations
Charlie Mace, Zhichao Carton Zeng, Annika H. G. Peter +4
Self-interacting dark matter (SIDM) theory predicts that dark matter halos experience core-collapse, a process where the halo's inner region rapidly increases in density and decrea…
Tidal evolution of cored and cuspy dark matter halos
Xiaolong Du, Andrew Benson, Zhichao Carton Zeng +9
The internal structure and abundance of dark matter halos and subhalos are powerful probes of the nature of dark matter. In order to compare observations with dark matter models, a…
