Abstract:Causal dissipative model is a plausible choice to explain the late accelerated epoch of universe. At the same time ΛCDM is considered to be standard model to explain the cosmological data corresponding to the late evolution of the universe. We consider a bulk viscus model in which the dissipation is driven by the bulk viscosity ζ = αρ 1/2 , described using the full causal Israel-Stewart theory. We computed the model parameters using the latest observational data (Pantheon). We contrasted this model with ΛCDM m… Show more
