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…
