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…

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…
