Constraints and cosmography of $$\Lambda $$ Λ CDM in presence of viscosity
Abstract In this work, we study two scenarios of the Universe filled by a perfect fluid following the traditional dark energy and a viscous fluid as dark matter. In this sense, we explore the most simple case for the viscosity in the Eckart formalism, a constant, and then, a polynomial function of t...
