Is the 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 CDM model and the dynamical dark energy parameterizations CDM and CDM, in which the dark energy (DE) equation of state is eith…
Dynamical Dark Energy models in light of the latest observations
Javier de Cruz Pérez, Adrià Gómez-Valent, Joan Solà Peracaula
In this paper, we study several models and parameterizations of dynamical dark energy (DE) that have been studied already in the past, in conjunction with the recently proposed mod…
Using non-DESI data to confirm and strengthen the DESI 2024 spatially-flat CDM cosmological parameterization result
Chan-Gyung Park, Javier de Cruz Perez, Bharat Ratra
We use a combination of Planck cosmic microwave background (CMB) anisotropy data and non-CMB data that include Pantheon+ type Ia supernovae (SNIa), Hubble parameter [], growt…
Updated observational constraints on spatially-flat and non-flat CDM and XCDM cosmological models
Javier de Cruz Perez, Chan-Gyung Park, Bharat Ratra
We study 6 LCDM models, with 4 allowing for non-flat geometry and 3 allowing for a non-unity lensing consistency parameter . We also study 6 XCDM models with a dynamical dark…
