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…
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…
Constraints on oscillating dark energy models
Aleksandra Kurek, Orest Hrycyna, Marek Szydlowski
The oscillating scenario of route to Lambda was recently proposed by us arXiv:0704.1651 as an alternative to a cosmological constant in a explanation of the current accelerating un…
Dissipative or Conservative cosmology with dark energy ?
Marek Szydlowski, Orest Hrycyna
All evolutional paths for all admissible initial conditions of FRW cosmological models with dissipative dust fluid (described by dark matter, baryonic matter and dark energy) are a…
