Self-interacting dark matter cusps around massive black holes
@article{Shapiro2014SelfinteractingDM, title={Self-interacting dark matter cusps around massive black holes}, author={Stuart L. Shapiro and Vasileios Paschalidis}, journal={Physical Review D}, year={2014}, volume={89}, pages={023506} }
We adopt the conduction fluid approximation to model the steady-state distribution of matter around a massive black hole at the center of a weakly collisional cluster of particles. By ``weakly collisional'' we mean a cluster in which the mean free time between particle collisions is much longer than the characteristic particle crossing (dynamical) time scale, but shorter than the cluster lifetime. When applied to a star cluster, we reproduce the familiar Bahcall-Wolf power-law cusp solution for…

This approximation reproduces the familiar Bahcall-Wolf quasistatic density cusp for the stars bound to the black hole and shows how the cusp halts the "gravothermal catastrophe" and causes the cluster to re-expand.

This work uses the Fermi Large Area Telescope to search for the γ-ray signature of p-wave annihilating DM from a spike around Sgr A* in the energy range 10 GeV-600 GeV, and places upper limits on the flux in ιray boxes originating from the Galactic Center.
