Do low-redshift observations open the doors to an open universe?
Deng Wang, Olga Mena, Salvatore Capozziello +1
The detection of a significant deviation from a zero curvature would have profound consequences for inflationary theories and fundamental physics. Relative to high-redshift Planck'…
Dark energy and neutrinos along the cosmic expansion history
Pietro Ghedini, Rasmi Hajjar, Olga Mena
Recent cosmological measurements are hinting that dark energy may evolve, with its equation of state, , even showing oscillatory patterns. In this work, we employ a…
Dark Energy Is Not That Into You: Variable Couplings after DESI DR2 BAO
Weiqiang Yang, Sibo Zhang, Olga Mena +2
In interacting dark energy (DE) and dark matter (DM) scenarios, the interaction function typically includes a coupling parameter that quantifies the strength of energy exchange…
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…
Probing the cold nature of dark matter
Weiqiang Yang, Supriya Pan, Eleonora Di Valentino +3
A pressureless dark matter component fits well with several cosmological observations. However, there are indications that cold dark matter may encounter challenges in explaining o…
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.…
Scale and redshift dependent limits on cosmic neutrino properties
Deng Wang, Olga Mena, Eleonora Di Valentino +1
Cosmological neutrino mass and abundance measurements are reaching unprecedented precision. Testing their stability versus redshift and scale is a crucial issue, as it can serve as…
