Thermodynamics of Genuine Kerr-Bertotti-Robinson Black Holes
David Kubiznak, Hryhorii Ovcharenko, Jiri Podolsky
We propose a thermodynamic description of the genuine Kerr-Bertotti-Robinson (Kerr-BR) black hole spacetimes. Contrary to previous studies, such solutions no longer have electric c…
Kerr-Newman and genuine Kerr black holes in the Bertotti-Robinson magnetic field
Hryhorii Ovcharenko, Jiri Podolsky
We present a spacetime that describes a rotating and charged black hole immersed in an external magnetic field. This exact solution to the Einstein-Maxwell equations has a surprisi…
New metric useful for studies of gravitational radiation from accelerating black holes of type D with any cosmological constant
Jiri Podolsky
We apply a convenient parametrization of all Plebanski-Demianski black holes of algebraic type D with the Kerr rotation, NUT twist, acceleration, electric and magnetic charges, and…
Uniqueness of stationary axisymmetric type D black holes with non-aligned electromagnetic field
Hryhorii Ovcharenko, Jiri Podolsky
We demonstrate the uniqueness of the spacetimes recently found by us in [H. Ovcharenko and J. Podolsky, Phys. Rev. D 112 (2025) 064076]. First, we prove that the conformal-to-Carte…
Static black holes in an external uniform electromagnetic field: Reissner-Nordstrom accelerating in Bertotti-Robinson
Hryhorii Ovcharenko, Jiri Podolsky
We provide a detailed analysis of the non-twisting subcase of the large class of type D black holes with a non-aligned electromagnetic field, presented recently in [H. Ovcharenko a…
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…
