Non-standard cosmic expansion histories: Neutrino decoupling and primordial nucleosynthesis signatures
D. Aristizabal Sierra, S. Gariazzo, A. Villanueva
Cosmological scenarios with a non-standard equation of state can involve ultrastiff fluids, understood as primordial fluids for which . Their energy densities can dominate…
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…
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…
Quantifying the tension between cosmological and terrestrial constraints on neutrino masses
Stefano Gariazzo, Olga Mena, Thomas Schwetz
The sensitivity of cosmology to the total neutrino mass scale is approaching the minimal values required by oscillation data. We study quantitatively possible tensions betwe…
