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…
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…
A quantitative comparison between velocity dependent SIDM cross sections constrained by the gravothermal and isothermal models
Shengqi Yang, Fangzhou Jiang, Andrew Benson +6
One necessary step for probing the nature of self-interacting dark matter (SIDM) particles with astrophysical observations is to pin down any possible velocity dependence in the SI…
A semi-analytic study of self-interacting dark-matter haloes with baryons
Fangzhou Jiang, Andrew Benson, Philip F. Hopkins +8
We combine the isothermal Jeans model and the model of adiabatic halo contraction into a simple semi-analytic procedure for computing the density profile of self-interacting dark-m…
Gravothermal solutions of SIDM halos: mapping from constant to velocity-dependent cross section
Shengqi Yang, Xiaolong Du, Zhichao Carton Zeng +4
The scale-free gravothermal fluid formalism has long proved effective in describing the evolution of self-interacting dark matter halos with a constant dark matter particle cross s…
Core-collapse, evaporation and tidal effects: the life story of a self-interacting dark matter subhalo
Zhichao Carton Zeng, Annika H. G. Peter, Xiaolong Du +5
Self-interacting dark matter (SIDM) cosmologies admit an enormous diversity of dark matter (DM) halo density profiles, from low-density cores to high-density core-collapsed cusps.…
Effects of neutrino mass and asymmetry on cosmological structure formation
Zhichao Zeng, Shek Yeung, Ming-Chung Chu
Light but massive cosmological neutrinos do not cluster significantly on small scales, due to their high thermal velocities. With finite masses, cosmological neutrinos become part…
Evidence of Neutrino Enhanced Clustering in a Complete Sample of Sloan Survey Clusters, Implying eV
Razieh Emami, Tom Broadhurst, Pablo Jimeno +7
The clustering amplitude of 7143 clusters from the Sloan Digital Sky Survey (SDSS) is found to increase with cluster mass, closely agreeing with the Gaussian random field hypothesi…
