Examining the Viscous Ricci Dark Energy Cosmological Model in General Theory of Gravitation

This study focuses on dynamically exploring Marder-type spacetime containing viscous Ricci dark energy within the framework of general relativity theory. To find a solution of the field equations, we use the relation between metric potentials and the average scale factor a(t)=(sinhβ1t)1/β2, this lea...

Description
Summary:This study focuses on dynamically exploring Marder-type spacetime containing viscous Ricci dark energy within the framework of general relativity theory. To find a solution of the field equations, we use the relation between metric potentials and the average scale factor a(t)=(sinhβ1t)1/β2, this leads to a seamless transition of the Universe from its initial decelerating phase to the current accelerating phase. Here, we have obtained the cosmological parameters and ωde-ω'de plane for the derived model. Also, dynamical features of the derived cosmological model are analyzed through diagrams.
