Redshift dependence and dipolar velocity corrections in cosmographic reconstructions through Type Ia supernova samples
Anna Chiara Alfano, Youri Carloni, Orlando Luongo +1
We perform a cosmographic analysis of Type Ia supernovae using the Pantheon+\&SH0ES, DES-SNY5 and Union3 compilations. We consider different redshift intervals, analyzed through a…
Do we really need alternatives to the 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 …
Alleviating the Hubble tension with the CDM model
Youri Carloni
We formulate a novel extension of the CDM model, named CDM, in which we consider an additional term at early times in order to alleviate the Hubble tension. This additi…
A barotropic alternative to Early Dark Energy for alleviating the tension
Youri Carloni, Orlando Luongo
We propose a cosmological scenario in which, beyond matter and radiation, an additional barotropic fluid with positive equation of state contributes to the cosmic energy budg…
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…
Phase-space analysis of dark energy models in non-minimally coupled theories of gravity
Youri Carloni, Orlando Luongo
We analyze scalar field dark energy models minimally and non-minimally coupled to gravity, postulating that a Yukawa-like interacting term is \emph{in form} equivalent for general…
Does dark energy really revive using DESI 2024 data?
Youri Carloni, Orlando Luongo, Marco Muccino
We investigate the impact of the Dark Energy Spectroscopic Instrument (DESI) 2024 data on dark energy scenarios. We thus analyze three typologies of models, the first in which the…
Phase-space analysis in non-minimal symmetric-teleparallel dark energy
Youri Carloni, Orlando Luongo
We modify the symmetric-teleparallel dark energy through the addition of a further Yukawa-like term, in which the non-metricity scalar, , is non-minimally coupled to a scalar fi…
Particle production from non-minimal coupling in a symmetry breaking potential transporting vacuum energy
Alessio Belfiglio, Youri Carloni, Orlando Luongo
We propose an inflationary scenario where the inflaton field is non-minimally coupled to spacetime curvature and inflation is driven by a vacuum energy symmetry breaking potential…
