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 comprehensive model for the formation and evolution of the faintest Milky Way dwarf satellites
Niusha Ahvazi, Andrew Benson, Laura V. Sales +4
In this study, we modify the semi-analytic model Galacticus in order to accurately reproduce the observed properties of dwarf galaxies in the Milky Way. We find that reproducing ob…
Gravitational Bose-Einstein Condensation of Vector/Hidden Photon Dark Matter
Jiajun Chen, Xiaolong Du, Mingzhen Zhou +2
We study the gravitational Bose-Einstein condensation of a massive vector field in the kinetic regime and the non-relativistic limit using non-linear dynamical numerical methods. G…
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…
Axion Star Explosions: A New Source for Axion Indirect Detection
Miguel Escudero, Charis Kaur Pooni, Malcolm Fairbairn +3
If dark matter is composed of axions, then axion stars form in the cores of dark matter halos. These stars are unstable above a critical mass, decaying to radio photons that heat t…
Soliton Merger Rates and Enhanced Axion Dark Matter Decay
Xiaolong Du, David J. E. Marsh, Miguel Escudero +4
Solitons are observed to form in simulations of dark matter (DM) halos consisting of bosonic fields. We use the extended Press-Schechter formalism to compute the mass function of s…
