Feeding the Void: Co-evolution of the SIDM-seeded Black Hole and the dark halo after core-collapse
Zhichao Carton Zeng, Annika H. G. Peter, Louis E. Strigari +3
While the gravothermal collapse of self-interacting dark matter (SIDM) halos provides a compelling mechanism for seeding supermassive black holes (BHs), the post-collapse macroscop…
The Sensitivity of Substructure Lensing to SIDM Core-collapse Model Variation
Charlie Mace, Birendra Dhanasingham, Zhichao Carton Zeng +4
Strong gravitational lensing has emerged as a powerful probe of dark matter substructure, and shows particularly strong promise as a test of self-interacting dark matter (SIDM). Th…
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…
A Comparison of Galacticus and COZMIC WDM Subhalo Populations
Jack Lonergan, Andrew Benson, Xiaolong Du
We present a comparative analysis of warm dark matter (WDM) subhalo populations generated by the semi-analytic model {\sc Galacticus} and the COZMIC suite of dark matter-only -b…
A Semi-Analytic model for Effects of Fuzzy Dark Matter Granule Perturbations on Orbital Motion
Yu Zhao, Andrew Benson, Xiaolong Du
In fuzzy dark matter scenarios, the quantum wave nature of ultralight axion-like particles generates stochastic density fluctuations inside dark matter halos. These fluctuations, k…
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…
