Description
In this presentation, we discuss the cosmological solutions of the Bianchi type−V spacetime filled with bulk viscous fluid and evolving cosmological Λ and Newtonian G parameters. We show that the model describes a universe that starts off with a negative cosmological term, dominated by non-relativistic matter and decelerated, that eventually becomes dark energy- dominated and hence expanding with acceleration, in concordance with current observations. Ongoing work in this direction will also be briefly discussed.
