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…
Scalar field cosmology in the energy phase-space -- unified description of dynamics
Marek Szydlowski, Orest Hrycyna
In this letter we apply dynamical system methods to study all evolutional paths admissible for all initial conditions of the FRW cosmological model with a non-minimally coupled to…
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…
Coupling constant constraints in a nonminimally coupled phantom cosmology
Marek Szydlowski, Orest Hrycyna, Aleksandra Kurek
In the paper we investigate observational constraints on coupling to gravity constant parameter using distant supernovae SNIa data, baryon oscillation peak (BOP), the cosmic mi…
