Is the $w_{0} w_{a}$ CDM cosmological parameterization evidence for dark energy dynamics partially caused by the excess smoothing of Planck PR4 CMB anisotropy data?

Javier de Cruz Pérez, Chan-Gyung Park, Bharat Ratra

We study the performance of the flat $Λ$ CDM model and the dynamical dark energy parameterizations $w_{0}$ CDM and $w_{0} w_{a}$ CDM, in which the dark energy (DE) equation of state is eithe…
