A dark-energy which behaves as the cosmological constant until a sudden phantom transition at very-low redshift ($z 4$\sigma$ disagreement between the local and high-redshift determinations of the Hubble constant, while maintaining the phenomenological success of the $\Lambda$CDM model with respect to the other observables. Here, we show that such a hockey-stick dark energy cannot solve the $H_0$ crisis. The basic reason is that the supernova absolute magnitude $M_B$ that is used to derive the…

Pseudoscalar sterile neutrino self-interactions in light of Planck, SPT and ACT data
We reassess the viability of a cosmological model including a fourth additional sterile neutrino species that self-interacts through a new pseudoscalar degree of freedom. We perform a series of
Implications of an Extended Dark Energy Model with Massive Neutrinos
Recently there have been reports of finding a lower bound on the neutrino mass parameter (Σm ν ) when using the Atacama Cosmology Telescope (ACT) and SPTpol data; however, these bounds on the Σm ν
Cosmographic Parameters in Model-independent Approaches
The cosmographic approach, a Taylor expansion of the Hubble function, has been used as a model-independent method to investigate the evolution of the universe in the presence of cosmological data.
The $H_0$ Olympics: A fair ranking of proposed models
Despite the remarkable success of the Λ Cold Dark Matter (ΛCDM) cosmological model, a growing discrepancy has emerged (currently measured at the level of ∼ 4 − 6σ) between the value of the Hubble
Multiband Gravitational Wave Cosmography with Dark Sirens
Gravitational waves might help resolve the tension between early and late Universe measurements of the Hubble constant, and this possibility can be enhanced with a gravitational wave detector in the
The inevitable manifestation of wiggles in the expansion of the late universe
Using the fact that the comoving angular diameter distance to last scattering is strictly constrained almost model-independently, we show that, for any model agreeing with ΛCDM on its background

Evidence for Cosmic Acceleration Is Robust to Observed Correlations between Type Ia Supernova Luminosity and Stellar Age
Type Ia supernovae (SNe Ia) are powerful standardizable candles for constraining cosmological models and provided the first evidence of the accelerated expansion of the universe. Their precision

H0 tension, phantom dark energy, and cosmological parameter degeneracies
Phantom dark energy (w<-1) can produce amplified cosmic acceleration at late times, thus increasing the value of H0 favored by CMB data and releasing the tension with local measurements of H0. We
Can late dark energy transitions raise the Hubble constant?
Late times dark energy transitions at redshifts $z \ll 0.1$ can raise the predicted value of the Hubble constant to the SH0ES value, $74.03\pm 1.42$ (km s$^{-1}$ Mpc$^{-1})$ or more, while providing

The evidence of environmental dependence of SN Ia luminosity has inspired recent discussion about whether the late-universe cosmic acceleration is still supported by supernova data. We adopt the
