Spatially flat universes with isotropic tidal forces
Fabio Scalco Dias, Leandro Gustavo Gomes, Luis Fernando Mello
We investigate the dynamics of the spatially flat universes submitted to isotropic tidal forces and adiabatic expansion under Einstein's equations. Surprisingly, the tendency to a…
On the intrinsically flat cosmological models in a lattice
Eduardo Bittencourt, Leandro G. Gomes, Grasiele B. Santos
In this manuscript we investigate the intrinsically flat (space-flat) spacetimes as viable cosmological models. We show that they have a natural geometric structure which is suitab…
The oscillatory anisotropy in the spatially flat cosmological models
Leandro G Gomes, Bruno B. Bizarria, Gabriel A. de Souza Silva +1
In this manuscript, we investigate the oscillatory behaviour of the anisotropy in the diagonal Bianchi-I spacetimes. Our starting point is a simplification of Einstein's equations…
The nonlinear patterns of the cosmic anisotropy in the late time universe
Leandro G. Gomes
In this manuscript, we investigate the patterns satisfied by the cosmological anisotropy under the hypothesis of the observers being co-moving with a perfect fluid whose induced sp…
Intrinsically symmetric cosmological model in the presence of dissipative fluids
E. Bittencourt, L. G. Gomes, G. B. Santos
Based upon the intrinsic symmetries approach to inhomogeneous cosmologies, we propose an exact solution to Einstein's field equations where the spatial sections are flat and the so…
Bianchi-I cosmology from causal thermodynamics
Eduardo Bittencourt, Leandro G. Gomes, Renato Klippert
We investigate diagonal Bianchi-I spacetimes in the presence of viscous fluids by using the shear and the anisotropic pressure components as the basic variables, where the viscosit…
