Observational Constraints on generalized dark matter properties in the presence of neutrinos with the final Planck release
Vikrant Yadav, Santosh Kumar Yadav, Anil Kumar Yadav
In this paper, we investigate an extension of the standard CDM model by allowing: a temporal evolution in the equation of state (EoS) of DM via Chevallier-Polarski-Linder parame…
