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…
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…
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…
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 firs…
Testing -attractor quintessential inflation against CMB and low-redshift data
William Giarè, Eleonora Di Valentino, Eric V. Linder +1
Due to universality and attractor properties, -attractor quintessential inflation establishes direct relations between inflationary observables such as the scalar tilt and…
Omnipotent dark energy: A phenomenological answer to the Hubble tension
Shahnawaz A. Adil, Ozgur Akarsu, Eleonora Di Valentino +4
This paper introduces the class of omnipotent dark energy (DE) models characterized by nonmonotonic energy densities that are capable of attaining negative values with correspondin…
Exploring the Growth Index : Insights from Different CMB Dataset Combinations and Approaches
Enrico Specogna, Eleonora Di Valentino, Jackson Levi Said +1
In this study we investigate the growth index , which characterizes the growth of linear matter perturbations, while analysing different cosmological datasets. We compare the…
