Do we really need alternatives to the $ω_{0} ω_{a}$ CDM parameterization after the DESI DR2?

Youri Carloni, Orlando Luongo, Marek Biesiada

We introduce a density-level pivot construction for the Chevallier-Polarski-Linder (CPL) parameterization by defining the normalized dark energy density $f_{p} \equiv f_{DE} (a_{p})$ …

Constraints on Chiral-Quintom dark energy after DESI DR2 and impact on unifying dark energy with inflation

Andronikos Paliathanasis, Tommaso Mengoni, Genly Leon +1

The recent data release DR2 from the Dark Energy Spectroscopic Instrument (DESI) has reinforced compelling evidence supporting the dynamical nature of dark energy. In this respect,…

Challenging the $ω_{0} ω_{a}$ CDM parametrization through rational expansions in view of DESI data release

Youri Carloni, Orlando Luongo, Marek Biesiada

In view of the new Dark Energy Spectroscopic Instrument (DESI) 2025 results, we analyze three types of \emph{Padé cosmology}, based on rational series making use of Padé approximan…
