Radius of the innermost stable circular orbit of black-holes with localized Astrophysical Dark Matter halo
We investigate the geodesic structure of a static, spherically symmetric black-hole in the background of a localized Astrophysical Dark Matter (ADM)-halo. The halo is modeled by a core-radius ($r_0$), regularized density profile that vanishes at the event horizon and exponential factor ensures the finite total halo mas...
