Slow-rolling down the curvature: a reassessment of the Planck constraints on inflation in a closed universe
Enrico Specogna, Tatevik Vardanyan, William Giarè +1
We revisit the Cosmic Microwave Background (CMB) constraints on the spatial curvature of the Universe, assessing how they change when the curvature parameter and the primordial inf…
Cosmographic Footprints of Dynamical Dark Energy
Elisa Fazzari, William Giarè, Eleonora Di Valentino
We introduce a novel cosmographic framework to trace the late-time kinematics of the Universe without assuming any underlying dynamics. The method relies on generalized Padé-$(2,1)…
Neutrino mass tension or suppressed growth rate of matter perturbations?
William Giarè, Olga Mena, Enrico Specogna +1
Assuming a minimal CDM cosmology with three massive neutrinos, the joint analysis of Planck cosmic microwave background data, DESI baryon acoustic oscillations, and distance mod…
Dark Energy Crosses the Line: Quantifying and Testing the Evidence for Phantom Crossing
Emre Özülker, Eleonora Di Valentino, William Giarè
Combinations of the most recent CMB, BAO, and SNeIa datasets, when analyzed using the CPL parametrization, , exclude CDM at in favor of a…
Resilience and implications of adiabatic CMB cooling
Ruchika, William Giarè, Elsa M. Teixeira +1
We investigate potential deviations from the standard adiabatic evolution of the cosmic microwave background (CMB) temperature, , using the latest Sunyaev-Zeldovich…
Implications of distance duality violation for the tension and evolving dark energy
Elsa M. Teixeira, William Giarè, Natalie B. Hogg +3
We investigate whether a violation of the distance duality relation (DDR), , connecting the angular diameter and luminosity distances, can explain the Hubb…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
Neutrino masses and mixing: Entering the era of subpercent precision
Francesco Capozzi, William Giarè, Eligio Lisi +3
We perform an updated global analysis of the known and unknown parameters of the standard framework as of 2025. The known oscillation parameters include three mixing angles $(…
An overview of what current data can (and cannot yet) say about evolving dark energy
William Giarè, Tariq Mahassen, Eleonora Di Valentino +1
Recent measurements of Baryon Acoustic Oscillations (BAO) and distance moduli from Type Ia supernovae suggest a preference for Dynamical Dark Energy (DDE) scenarios characterized b…
A solution to the S8 tension through neutrino-dark matter interactions
Lei Zu, William Giarè, Chi Zhang +3
Neutrinos and dark matter (DM) are two of the least understood components of the Universe, yet both play crucial roles in cosmic evolution. Clues about their fundamental properties…
