101. Bondi-type accretion onto a Kerr black hole in the kinetic regime

Dr Mehrab Momennia (UMSNH)

The dark matter-black hole interaction is modeled with the help of the accretion of a Vlasov gas into a rotating Kerr black hole. We provide exact analytic expressions for the particle, mass, and angular momentum accretion rates in the form of integrals. These integrals are computed numerically and compared to more explicit relations in the slow-rotation approximation. The explicit analytic...
