Example of cross-polarized standing gravitational waves
Krzysztof Głód, Szymon Sikora, Sebastian J. Szybka
We use a cosmological counterpart of the cylindrical Halilsoy solution to illustrate properties of cross-polarized standing gravitational waves.
Construction of the cosmological model with periodically distributed inhomogeneities with growing amplitude
Szymon Sikora, Krzysztof Głód
We construct an approximate solution to the cosmological perturbation theory around Einstein-de Sitter background up to the fourth-order perturbations. This could be done with the…
1+1+2 covariant formulation of light propagation in spacetime
Krzysztof Głód
We present a covariant approach to the problem of light beam propagation in a spacetime. We develop our considerations within the framework of classical geometric optics in general…
Perturbatively constructed cosmological model with periodically distributed dust inhomogeneities
Szymon Sikora, Krzysztof Głód
We constructed a simple cosmological model which approximates the Einstein-de Sitter background with periodically distributed dust inhomogeneities. By taking the metric as a power…
Example of an inhomogeneous cosmological model in the context of backreaction
Szymon Sikora, Krzysztof Głód
In this article, we present an example of an inhomogeneous cosmological model, which is inspired by the linear perturbation theory. The metric of this model can be described as the…
Inhomogeneity effect in Wainwright-Marshman space-times
Sebastian J. Szybka, Krzysztof Głód, Michał J. Wyrȩbowski +1
Green and Wald have presented a mathematically rigorous framework to study, within general relativity, the effect of small scale inhomogeneities on the global structure of space-ti…
