Probing late-time deviations from CDM with a quadratic dark energy expansion
Sehjal Khandelwal, Abraão J. S. Capistrano, Suresh Kumar +1
We investigate the observational viability of a quadratic dark energy expansion (QDEE) model as a phenomenological extension of the standard cosmological framework…
Probing dynamical dark energy with late-time data: Evidence, tensions, and the limits of the CDM framework
Tengpeng Xu, Suresh Kumar, Yun Chen +4
We test the dynamical dark-energy CDM (CPL) framework against CDM using CMB anisotropies and lensing together with DESI DR2, SDSS-IV, transverse/angular BAO (BAOtr), and…
CDM cosmology from a type-II minimally modified gravity
Ãzgür Akarsu, Antonio De Felice, Eleonora Di Valentino +5
We integrate CDM, a promising scenario for alleviating cosmological tensions, into VCDM, a type-II minimally modified gravity. This promotes the scenario to a fully pre…
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 CDM and its sign-switching extension, CDM, using a suite of Gaussian and exact non-Gaussian consist…
-CDM: A promising phenomenological extension of the standard model of cosmology
Suresh Kumar
We investigate a phenomenological extension of the standard CDM framework, the -CDM model, in which the total energy density of the universe is expanded in powers…
