Dynamics and cosmological constraints on Brans-Dicke cosmology
Orest Hrycyna, Marek Szydlowski, Michal Kamionka
We investigate observational constraints on the Brans-Dicke cosmological model using observational data coming from distant supernovae type Ia, the Hubble function measureme…
Constraining Palatini cosmological models using GRB data
Michal Kamionka
New constraints on previously investigated Palatini cosmological models [arXiv:1109.3420] have been obtained by adding Gamma Ray Burst data [arXiv:1205.2954].
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…
Smoothed quantum fluctuations and CMB observations
Jakub Mielczarek, Michal Kamionka
In this paper we investigate power spectrum of a smoothed scalar field. The smoothing leads to the regularisation of the UV divergences and can be related with the internal structu…
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…
