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'…

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…

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.…

Updating neutrino mass constraints with Background measurements

Deng Wang, Olga Mena, Eleonora Di Valentino +1

Low-redshift probes, such as Baryon Acoustic Oscillations (BAO) and Supernovae Ia luminosity distances, have been shown to be crucial for improving the bounds on the total neutrino…
