Challenging the 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…
Parameterizing quasi-quintessence and quasi-phantom fields without the nearly flat potential approximation
Anna Chiara Alfano, Youri Carloni
An alternative dark energy description based on a generalized K-essence scenario is here explored. In particular, we consider a \emph{quasi-quintessence} and/or \emph{quasi-phantom…
Addressing the tension through matter with pressure and no early dark energy
Youri Carloni, Orlando Luongo, Marco Muccino
We propose that the Hubble tension arises due to an unaccounted additional component, that behaves as \emph{matter with pressure}. We demonstrate that this fluid remains subdominan…
Stability analysis of dilaton-inspired scalar field within the geometrical trinity of gravity
Youri Carloni, Orlando Luongo, Andronikos Paliathanasis
We investigate the dynamics of the dilaton-inspired scalar field, formally rewritten by means of a Brans-Dicke Lagrangian, within the framework of \emph{geometrical trinity of grav…
