Spinoptics in the Kerr Spacetime: Polarized Wave Scattering
Valeri P. Frolov, Alex Koek
We study propagation of high-frequency electromagnetic and gravitational waves in the gravitational field of a rotating black hole. Due to the interaction of the spin of the field…

Regular black holes inspired by quasi-topological gravity
Valeri P. Frolov, Alex Koek, Jose Pinedo Soto +1
Recently it was demonstrated that by adding to the Einstein-Hilbert action a series in powers of the curvature invariants with specially chosen coefficients one can obtain a theory…

Motion of a weakly charged rotating black hole in a homogeneous electromagnetic field
Valeri P. Frolov, Alex Koek
In this paper we consider a rotating black hole with electric and magnetic monopole charges that moves in a static homogeneous electromagnetic field. We assume that both the charge…
