Rastall cosmology
J. C. Fabris, O. F. Piattella, D. C. Rodrigues +2
We review the difficulties of the generalized Chaplygin gas model to fit observational data, due to the tension between background and perturbative tests. We argue that such issues…
Inhomogeneous Universe in f(T) Theory
Manuel E. Rodrigues, M. Hamani Daouda, M. J. S. Houndjo +2
We obtain the equations of motions of the theory considering the Lemaître-Tolman-Bondi's metric for a set of diagonal and non-diagonal tetrads. In the case of diagonal tetra…
Scalar models for the unification of the dark sector
Mahamadou H. Daouda, Julio C. Fabris, Oliver F. Piattella
We review the difficulties of the generalized Chaplygin gas model to fit observational data, due to the tension between background and perturbative tests. We argue that such issues…
Anisotropic fluid for a set of non-diagonal tetrads in f(T) gravity
M. Hamani Daouda, Manuel E. Rodrigues, M. J. S. Houndjo
We consider gravity for a Weitzenbock spherically symmetric and static spacetime, where the metric is projected in the tangent space to the manifold for a set of non-diagona…
