Solutions of the Einstein equations for a black hole surrounded by a galactic halo
read the original abstract
Various profiles of matter distribution in galactic halos (such as Navarro-Frenk-White, Burkert, Hernquist, Moore, Taylor-Silk and others) are considered here as the source term for the Einstein equations. We solve these equations and find exact solutions which represent the metric of a central black hole immersed in a galactic halo. Even though in the general case the solution is numerical, very accurate general analytical metric, which includes all the particular models, are found in the astrophysically relevant regime, when the mass of the galaxy is much smaller than the characteristic scale in the halo.

Geometric properties of slowly rotating black holes embedded in matter environments
The rotation of a surrounding dark-matter halo shifts the light ring, ISCO, epicyclic frequencies, and resonance locations of a slowly spinning black hole in a way that depends on the halo's angular velocity.

Scalar and Electromagnetic Perturbations around a Black Hole with a Topological Defect: Quasinormal Modes and Quasi-bound States in a Plasma Medium
Plasma and topological defect k suppress scalar QNM frequencies and allow axial EM quasi-bound states only for homogeneous plasma below a k- and l-dependent critical frequency.

Long-lived quasinormal frequencies for regular black hole supported by the Einasto profile in the presence of the magnetic field
For Einasto-supported regular black holes, larger effective scalar mass and certain halo parameters suppress the quasinormal damping rate, producing long-lived modes and shifting grey-body factors toward higher frequencies.
