Reconstruction of f(R, T) gravity describing matter dominated and accelerated phases
Reconstruction gravity describing dominated accelerated phases
2011/10/12
We investigate the cosmological reconstruction in modified f(R,T) gravity, where R is the Ricci scalar and T the trace of the stress-energy tensor. Special attention is attached to the case in which t...
Probing bulk viscous matter-dominated models with Gamma-ray bursts
Probing viscous matter-dominated Gamma-ray bursts
2011/9/27
In this paper we extend the range of consistency of a constant bulk viscosity model to redshifts up to $z\sim 8.1$. In this model the dark sector of the cosmic substratum is a viscous fluid with press...
