Cosmological constraints on the interacting viscous dark matter and decaying vacuum energy models
Lokesh Chander, C P Singh
We investigate an interacting dark sector scenario in which a deviation from the standard dilution law of cold dark matter is parametrized by a perturbative correction , thereby…

Cosmological Dynamics of Matter Creation with Modified Chaplygin Gas and Bulk Viscosity
Yogesh Bhardwaj, C P Singh
This work presents a comprehensive investigation of a novel cosmological model that unifies the Modified Chaplygin Gas (MCG) equation of state with gravitationally induced matter c…
