Light deflection in axially symmetric stationary spacetimes filled with a moving medium

Christian Pfeifer, Barbora Bezděková, Oleg Yu. Tsupko

The deflection of light rays near gravitating objects can be influenced not only by gravity itself but also by the surrounding medium. Analytical studies of such effects are possib…

Kerr isolated horizon revisited: Caustic-free congruence and adapted tetrad

Aleš Flandera, David Kofroň, Tomáš Ledvinka

We revisit the near-horizon description of the Kerr space-time in the isolated horizon formalism using a non-twisting null geodesic congruence and eliminate the coordinate and geod…

Double Wick rotations between symmetries of Taub-NUT, near-horizon extreme Kerr, and swirling spacetimes

Aimeric Colléaux, Ivan Kolář, Tomáš Málek

We explicitly show that certain 4-dimensional infinitesimal group actions with 3-dimensional orbits are related by double Wick rotations. In particular, starting with the symmetrie…

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…

Linear perturbations of Kerr black hole in quadratic gravity

Simon Knoska, David Kofron, Robert Svarc

Employing the Newman-Penrose formalism and following the classic Teukolsky-like approach, we linearise the field equations of quadratic gravity on the Kerr background and combine t…

Teleparallel gravity from the principal bundle viewpoint

Sebastian Brezina, Eugenia Boffo, Martin Krššák

We examine whether the Teleparallel Equivalent of General Relativity (TEGR) can be formulated as a gauge theory in the language of connections on principal bundles. We argue in fav…

Conical singularity in spacetimes with NUT is observer-dependent

Ivan Kolář, Pavel Krtouš, Maciej Ossowski

We discuss the issue of defining and measuring conical deficits (conicity) in spacetimes with the torsion singularity such as the Misner string in Taub--NUT spacetime. We propose a…

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…

On the uniqueness of the Kerr-(A)dS metric as a type II(D) solution in six dimensions

David Kokoška, Marcello Ortaggio

We study the class of six-dimensional -vacuum spacetimes which admit a non-degenerate multiple Weyl aligned null direction l (thus being of Weyl type~II or more special) with 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…

Emergent Lorentzian dispersion relations from a Euclidean scalar-tensor theory
