Using 12 neutrino-emitting Seyfert galaxies and the Cepheid-plus-TRGB distance to NGC 1068, the authors obtain the first neutrino-based Hubble constant estimate, H0 = 49+40-30 km/s/Mpc, with slope beta = 0.67+0.16-0.25.

Measurement of the Hubble constant with high-energy neutrinos
Using 12 neutrino-emitting Seyfert galaxies and the Cepheid-plus-TRGB distance to NGC 1068, the authors obtain the first neutrino-based Hubble constant estimate, H0 = 49+40-30 km/s/Mpc, with slope beta = 0.67+0.16-0.25.
