Gyratons on direct-product spacetimes
Hedvika Kadlecova, Andrei Zelnikov, Pavel Krtous +1
We present and analyze exact gyraton and nonexpanding gravitational wave solutions of algebraic type II on backgrounds which are a direct-product of two 2-spaces of constant curvat…
Radiation generated by accelerating and rotating charged black holes in (anti-)de Sitter space
Jiri Podolsky, Hedvika Kadlecova
Asymptotic behaviour of gravitational and electromagnetic fields of exact type D solutions from the large Plebanski-Demianski family of black hole spacetimes is analyzed. The ampli…
General Kundt spacetimes in higher dimensions
Jiri Podolsky, Martin Zofka
We investigate a general metric of the Kundt class of spacetimes in higher dimensions. Geometrically, it admits a non-twisting, non-shearing and non-expanding geodesic null congrue…
Photon rockets in (anti-)de Sitter universe
Jiri Podolsky
A class of exact solutions of Einstein's equations is presented which describes accelerating photon rockets in de Sitter and anti-de Sitter universe. These are particular members o…
Robinson-Trautman spacetimes with an electromagnetic field in higher dimensions
Marcello Ortaggio, Jiri Podolsky, Martin Zofka
We investigate higher dimensional Robinson-Trautman spacetimes with an electromagnetic field aligned with the hypersurface orthogonal, non-shearing, expanding geodesic null congrue…
Chaotic motion in Kundt spacetimes
Jiri Podolsky, David Kofron
We demonstrate that geodesics in exact vacuum Kundt gravitational waves may exhibit a highly complicated behaviour. In fact, as in the previously studied case of non-homogeneous pp…
