Numerical solutions of Einstein field equations with radial dark matter

Abstract: We study a static spherically symmetric problem with a black hole and radially directed geodesic flows of dark matter. The obtained solutions have the following properties. At large distances, the gravitational field produces constant velocities of circular motion, i.e. flat rotation curves. At smaller distances, the field switches to Newtonian regime, then to Schwarzschild regime. Deviations from Schwarzschild regime start below the gravitational radius. The dark matter prevents the creation of event horizon,… Show more

“…As a suitable environment, we use the model of null radial dark matter (NRDM, [41]). This model considers a static spherically symmetric distribution of dark matter, described by a perfect fluid EOS of the form ρ = p r , p t = 0.…”

“…In the central region of this solution, the redshift A-profile rapidly drops with a decreasing radius. In [41] such behavior was called red supershift. It is closely related to the mass inflation phenomenon found in a black hole model with counterstreaming matter flows [42].…”
