Cosmic acceleration from modified gravity with Palatini formalism
A. Borowiec, M. Kamionka, A. Kurek +1
We study new FRW type cosmological models of modified gravity treated on the background of Palatini approach. These models are generalization of Einstein gravity by the presence of…
Observational hints on the Big Bounce
Jakub Mielczarek, Michal Kamionka, Aleksandra Kurek +1
In this paper we study possible observational consequences of the bouncing cosmology. We consider a model where a phase of inflation is preceded by a cosmic bounce. While we consid…
Bayesian analysis of the backreaction models
Aleksandra Kurek, Krzysztof Bolejko, Marek Szydlowski
We present the Bayesian analysis of four different types of backreation models, which are based on the Buchert equations. In this approach, one considers a solution to the Einstein…
From model dynamics to oscillating dark energy parameterisation
Aleksandra Kurek, Orest Hrycyna, Marek Szydlowski
We develop here a relatively simple description of dark energy based on the dynamics of non-minimally coupled to gravity phantom scalar field which, in limit, corresponds to cosmol…
AIC, BIC, Bayesian evidence against the interacting dark energy model
Marek Szydlowski, Adam Krawiec, Aleksandra Kurek +1
Recent astronomical observations have indicated that the Universe is in the phase of accelerated expansion. While there are many cosmological models which try to explain this pheno…
Dark energy FRW cosmology - dynamical system reconstruction
Marek Szydlowski, Aleksandra Kurek
We develop a simple method of dark energy reconstruction using a geometrical form of the luminosity-distance relation. In this method the FRW dynamical system with dark energy is r…
