Unifying dark components and crossing the phantom divide with a classical Dirac field
Mauricio Cataldo, Luis P. Chimento
In this paper we consider a spatially flat Friedmann-Robertson-Walker (FRW) cosmological model whit cosmological constant, containing a stiff fluid and a classical Dirac field. The…

An accelerated closed universe
Sergio del Campo, Mauricio Cataldo, Francisco Pena
We study a model in which a closed universe with dust and quintessence matter components may look like an accelerated flat Friedmann-Robertson-Walker (FRW) universe at low redshift…

Scalar fields in an anisotropic closed universe
Mauricio Cataldo, Sergio del Campo
We study in this article a class of homogeneous, but anisotropic cosmological models in which shear viscosity is included. Within the matter content we consider a component (the qu…
