Bypassed Core Formation in Milky Way-Mass SIDM Halos: Implications for the Local Group Past-Pericenter Scenario

Zhichao Carton Zeng, Odelia V. Hartl, Louis E. Strigari +4

We consider a scenario in which the Milky Way (MW) and M31 have had a previous pericentric passage, and investigate its compatibility with self-interacting dark matter (SIDM). Usin…

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…

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…

Diversity and universality: evolution of dwarf galaxies with self-interacting dark matter

Zhichao Carton Zeng, Annika H. G. Peter, Xiaolong Du +4

Dark matter halos with self-interacting dark matter (SIDM) experience a unique evolutionary phenomenon, in that their central regions eventually collapse to high density through th…

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…

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…

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…
