Physical Effects in the Vicinity of Black Holes
Alex Koek
General relativity, a theory that is already over a century old, is still the best theory that we have to describe the universe at energy scales where only the gravitational force…
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…
Motion of Rotating Black Holes in Homogeneous Scalar Fields: A General Case
Valeri P. Frolov, Alex Koek
In this paper we consider the motion of a rotating black hole through a static, homogeneous, massless scalar field. In the general case, a constant vector of the field gradient can…
Gravitational lensing, memory and the Penrose limit
Valeri P. Frolov, Alex Koek
In this paper, we discuss the gravitational field of ultrarelativistic extended spinning objects. For this purpose, we use a solution of the linearized gravitational equations obta…
