Intriguingly, it also offers a possible solution to the discrepant cosmological measurements of $H_0$ and $\\sigma_8$. We show here that delaying the onset of neutrino free-streaming until close to the epoch of matter-radiation equality can naturally accommodate a larger value for the Hubble constant $H_0=72.3 \\pm 1.4$ km/s/Mpc and a lower value of the matter fluctuations $\\sigma_8=0.786\\pm 0.020$, while not degrading the fit to the cosmic microwave background (CMB) dam","authors_text":"Christina D.
