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…
Updated Constraints on Omnipotent Dark Energy: A Comprehensive Analysis with CMB and BAO Data
Enrico Specogna, Shahnawaz A. Adil, Emre Ozulker +4
In this work, we present updated observational constraints on the parameter space of the DMS20 dark energy model, a member of the omnipotent dark energy (ODE) class. Our analysis c…
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 mo…
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.…
Planck-PR4 anisotropy spectra show (better) consistency with General Relativity
Enrico Specogna, William Giarè, Eleonora Di Valentino
We present the results from a series of analyses on two parametric tests of gravity that modify the growth of linear, sub-horizon matter perturbations in the CDM model. The fir…
