Baryon acoustic oscillation measurements by the Dark Energy Spectroscopic Instrument
(Data Release 1) have revealed exciting results that show evidence for dynamical dark …

Observational cosmology is rapidly closing in on a measurement of the sum M ν of neutrino
masses, at least in the simplest cosmologies, while opening the door to probes of non …

The early dark energy (EDE) model is one of the promising solutions to the Hubble tension.
One of the successes of the EDE model is that it can provide a similar fit to the Λ CDM model …

The Λ CDM model has successfully explained a wide range of cosmological observations,
but is increasingly challenged by the emergence of cosmological tensions, particularly the …

In this work we investigate, through a Bayesian study, the ability of a local low matter density
$\Omega_ {\rm M} $, in discrepancy with the value usually inferred from the CMB angular …

The EDE model is one of the promising solutions to the long-standing Hubble tension. This
paper investigates the status of several EDE models in light of recent BAO observations from …

The Hubble tension between direct measurements of the expansion rate and the prediction
of the $\Lambda $ CDM cosmological model calibrated on the Cosmic Microwave …

The question of whether the massive sterile neutrinos exist remains a crucial unresolved
issue in both particle physics and cosmology. We explore the cosmological constraints on …

In this paper, we investigate the impact of the lensing anomaly in Planck cosmic microwave
background (CMB) data on the nature of dark energy (DE). We constrain the state equation …

Given the remarkable success of the $\Lambda $ CDM model in fitting various cosmological
observations, a pertinent question in assessing the phenomenological viability of modified …
