Joint measurement of the ultra-high-energy neutrino spectrum and cross section
Victor B. Valera, Mauricio Bustamante, Olga Mena
Soon, a new generation of neutrino telescopes, presently under planning, will target the discovery of ultra-high-energy (UHE) neutrinos of cosmic origin, with energies higher than…
Lensing impact on cosmic relics and tensions
William Giarè, Olga Mena, Eleonora Di Valentino
Cosmological bounds on neutrinos and additional hypothetical light thermal relics, such as QCD axions, are currently among the most restrictive ones. These limits mainly rely on Co…
Shedding light on the tension with supernova neutrinos
Rasmi Hajjar, Sergio Palomares-Ruiz, Olga Mena
One long-standing tension in the determination of neutrino parameters is the mismatched value of the solar mass square difference, , measured by different experiments: t…
On the dark radiation role in the Hubble constant tension
Stefano Gariazzo, Olga Mena
Dark radiation, parameterized in terms of , has been considered many times in the literature as a possible remedy in alleviating the Hubble constant () tension. W…
Do the Early Galaxies observed by JWST disagree with Planck's CMB polarization measurements?
Matteo Forconi, Ruchika, Alessandro Melchiorri +2
The recent observations from the James Webb Space Telescope have led to a surprising discovery of a significant density of massive galaxies with masses of $M \ge 10^{10.5} M_{\odot…
Impact of the damping tail on neutrino mass constraints
Eleonora Di Valentino, Stefano Gariazzo, William Giarè +1
Model-independent mass limits assess the robustness of current cosmological measurements of the neutrino mass scale. Consistency between high-multipole and low-multiple Cosmic Micr…
