Hidden symmetries and separability structures of Ovcharenko-Podolský and conformal-to-Carter spacetimes
Finnian Gray, David Kubiznak, Hryhorii Ovcharenko +1
Recently, a remarkable new class of spacetimes describing black holes immersed in a non-aligned electromagnetic field has been found. While still of type D, this class goes beyond…
A novel class of rotating black holes with non-aligned electromagnetic field
Hryhorii Ovcharenko, Jiri Podolsky
We present a new class of expanding and twisting solutions to the Einstein-Maxwell equations of algebraic type D, where the null eigendirections of the Faraday tensor are not align…
New class of rotating charged black holes with nonaligned electromagnetic field
Hryhorii Ovcharenko, Jiří Podolský
We present a large family of twisting and expanding solutions to the Einstein-Maxwell equations of algebraic type D, for which the two double principal null directions (PNDs) of th…
Kerr black hole in a uniform Bertotti-Robinson magnetic field: An exact solution
Jiri Podolsky, Hryhorii Ovcharenko
A new class of exact spacetimes in Einstein's gravity, which are Kerr black holes immersed in an external magnetic (or electric) field that is asymptotically uniform and oriented a…
Near-horizon behavior of nonequatorial accelerated particle motion and high energy particle collisions
H. V. Ovcharenko, O. B. Zaslavskii
We consider motion of a particle in the background of a stationary axially symmetric generic black hole. A particle experiences the action of a force of unspecified nature. We requ…
Naked and truly naked rotating black holes
H. V. Ovcharenko, O. B. Zaslavskii
Previously, it was noticed that in some space-times with Killing horizons some curvature components, responsible for tidal forces, small or even zero in the static frame, become en…
Revisiting black holes of algebraic type D with a cosmological constant
Hryhorii Ovcharenko, Jiri Podolsky, Marco Astorino
As an extension of our previous work [1] (arXiv:2409.02308), we study a complete family of type D black holes with Kerr-like rotation, NUT twist, acceleration, electric and magneti…
