Melvin universe as a limit of the C-metric
Lenka Havrdova, Pavel Krtous
It is demonstrated that the Melvin universe representing the spacetime with a strong 'homogeneous' electric field can by obtained from the spacetime of two accelerated charged blac…
Evolution of high-frequency gravitational waves in some cosmological models
Otakar Svitek, Jiri Podolsky
We investigate Isaacson's high-frequency gravitational waves which propagate in some relevant cosmological models, in particular the FRW spacetimes. Their time evolution in Fourier…
Interpreting the C-metric
J. B. Griffiths, P. Krtous, J. Podolsky
The basic properties of the C-metric are well known. It describes a pair of causally separated black holes which accelerate in opposite directions under the action of forces repres…
Electromagnetic field near cosmic string
Pavel Krtous
The retarded Green function of the electromagnetic field in spacetime of a straight thin cosmic string is found. It splits into a geodesic part (corresponding to the propagation al…
Robinson-Trautman spacetimes in higher dimensions
Jiri Podolsky, Marcello Ortaggio
As an extension of the Robinson-Trautman solutions of D=4 general relativity, we investigate higher dimensional spacetimes which admit a hypersurface orthogonal, non-shearing and e…
Ultrarelativistic sources in nonlinear electrodynamics
Jiri Bicak, David Kubiznak
The fields of rapidly moving sources are studied within nonlinear electrodynamics by boosting the fields of sources at rest. As a consequence of the ultrarelativistic limit the del…
Asymptotic structure of radiation in higher dimensions
Pavel Krtous, Jiri Podolsky
We characterize a general gravitational field near conformal infinity (null, spacelike, or timelike) in spacetimes of any dimension. This is based on an explicit evaluation of the…
Fields of accelerated sources: Born in de Sitter
Jiri Bicak, Pavel Krtous
This paper deals thoroughly with the scalar and electromagnetic fields of uniformly accelerated charges in de Sitter spacetime. It gives details and makes various extensions of our…
Accelerating Kerr-Newman black holes in (anti-)de Sitter space-time
J. Podolsky, J. B. Griffiths
A class of exact solutions of the Einstein-Maxwell equations is presented which describes an accelerating and rotating charged black hole in an asymptotically de Sitter or anti-de…
