Supernovae constraints on dark energy and modified gravity models
M. C. Bento, O. Bertolami, N. M. C. Santos +1
We use the Type Ia Supernova gold sample to constrain the parameters of dark energy models namely the Cardassian, Dvali-Turner (DT) and generalized Chaplygin gas (GCG) models. In o…
Generalized Chaplygin Gas in a modified gravity approach
T. Barreiro, A. A. Sen
We study the generalized Chaplygin gas (GCG) scenario in a modified gravity approach. That is, we impose that our universe has a pure dust configuration, and allow for a modificati…
The Revival of the Unified Dark Energy-Dark Matter Model ?
M. C. Bento, O. Bertolami, A. A. Sen
We consider the generalized Chaplygin gas (GCG) proposal for unification of dark energy and dark matter and show that it admits an unique decomposition into dark energy and dark ma…
WMAP Constraints on a Quintessence Model
T. Barreiro, M. C. Bento, N. M . C. Santos +1
We use the results from the Wilkinson Microwave Anisotropy Probe (WMAP) for the locations of peaks and troughs of the Cosmic Microwave Background (CMB) power spectrum, together wit…
WMAP Constraints on Quintessence
T. Barreiro, M. C. Bento, N. M. C. Santos +1
We use recent results from the Wilkinson Microwave Anisotropy Probe (WMAP) for the locations of peaks and troughs of the Cosmic Microwave Background (CMB) power spectrum, together…
