Abstract

In the original language

Assuming a sufficiently general form for the matter distribution function of a galactic halo, we have derived solutions to the Einstein-Maxwell equations describing a charged black hole embedded in such a halo, while also allowing for a nonzero cosmological constant. These solutions generalize our earlier results for neutral black holes in asymptotically flat spacetime. As specific realizations of the general distribution, we consider the Hernquist, Navarro-Frenk-White, Burkert, Taylor-Silk, and Moore halo profiles, thereby capturing a broad range of astrophysically motivated scenarios.
