Gamma Ray Bursts as Cosmological Probes
O. Bertolami, P. T. Silva
We discuss the prospects of using Gamma Ray Bursts (GRBs) as high-redshift distance estimators, and consider their use in the study of two dark energy models, the Generalized Chapl…
Generalized Chaplygin gas model, supernovae and cosmic topology
M. C. Bento, O. Bertolami, M. J. Rebouças +1
In this work we study to which extent the knowledge of spatial topology may place constraints on the parameters of the generalized Chaplygin gas (GCG) model for unification of dark…
Gamma-ray bursts as dark energy-matter probes in the context of the generalized Chaplygin gas model
O. Bertolami, P. T. Silva
In this paper we consider the use of Gamma Ray Bursts (GRBs) as distance markers to study the unification of dark energy and dark matter in the context of the so-called Generalized…
Expected constraints on the generalized Chaplygin equation of state from future supernova experiments and gravitational lensing statistics
P. T. Silva, O. Bertolami
This paper aims to study the use of future SNAP data together with the result of searches for strong gravitational lenses in future large quasar surveys to constrain the Generalize…
Fitting BOOMERANG and MAXIMA-1 data with a Einstein-Yang-Mills Cosmological Model
M. C. Bento, O. Bertolami, P. T. Silva
We analyse the implications of recent Cosmic Microwave Background (CMB) data for a specific cosmological model, based on the higher-dimensional Einstein-Yang-Mills System compactif…
