“NANOGrav meets Hot New Early Dark Energy and the origin of neutrino mass”: We show that in the Hot NEDE model, both the Hubble tension and the NANOGrav observations could be a signature of the origin of neutrino mass: https://arxiv.org/abs/2307.03091

Euclid will help us to determine the source of the Hubble tension. Its measurements of Large Scale Structure formation will help us to test and constrain models and provide valuable insight into New Early Dark Energy (NEDE) as a possible solution to the H0 and S8 tensions.
