The Integrated Sachs-Wolfe Effect in the Bulk Viscous Dark Energy Model
B. Mostaghel, H. Moshafi, S. M. S. Movahed
We examine linear perturbation theory to evaluate the contribution of viscosity coefficient in the growing of dark matter perturbations in the context of the bulk viscous dark ener…

Non-minimal Derivative Coupling Scalar Field and Bulk Viscous Dark Energy
Behrang Mostaghel, Hossein Moshafi, S. M. S. Movahed
Inspired by thermodynamical dissipative phenomena, we consider bulk viscosity for dark fluid in a spatially flat two-component Universe. Our viscous dark energy model represents Ph…
