Spherically Symmetric Configurations in Unimodular Gravity
Júlio C. Fabris, Mahamadou Hamani Daouda, Hermano Velten
Unimodular gravity (UG) is considered, under many aspects, equivalent to General Relativity (GR), even if the theory is invariant under a more restricted diffeomorphic class of tra…
Brans-Dicke unimodular gravity
Alexandre M. R. Almeida, Júlio C. Fabris, Mahamadou Hamani Daouda +3
We propose a unimodular version of the Brans-Dicke theory designed with a constrained Lagrangian formulation. The resulting field equations are traceless. The vacuum solutions in t…
Rastall's Cosmology and its Observational Constraints
J. C. Fabris, O. F. Piattella, D. C. Rodrigues +1
The Rastall's theory is a modification of General Relativity touching one of the cornestone of gravity theory: the conservation laws. In Rastall's theory, the energy-momentum tenso…
Testing the Rastall's theory using matter power spectrum
C. E. M. Batista, J. C. Fabris, M. Hamani Daouda
The Rastall's theory is a modification of the General Relativity theory leading to a different expression for the conservation law in the matter sector compared with the usual one.…
