Statistical consistency of sign-switching vacuum energy with cosmological observations

Sehjal Khandelwal, Abraão J. S. Capistrano, Suresh Kumar

We assess dataset agreement and late-time predictive adequacy in $Λ$ CDM and its sign-switching extension, $Λ_{s}$ CDM, using a suite of Gaussian and exact non-Gaussian consisten…

Probing dynamical dark energy with late-time data: Evidence, tensions, and the limits of the $w_{0} w_{a}$ CDM framework

Tengpeng Xu, Suresh Kumar, Yun Chen +2

We test the dynamical dark-energy $w_{0} w_{a}$ CDM (CPL) framework against $Λ$ CDM using CMB anisotropies and lensing together with DESI DR2, SDSS-IV, transverse/angular BAO (BAOtr), and…
