Dark Energy Survey Year 1 results: a precise H0 measurement from DES Y1, BAO, and D/H data
DES collaboration, et al
Combine DES Y1 clustering and WL data with BAO and BBN experiments to constrain the Hubble constant. Assuming a flat LCDM model with minimal neutrino mass (sum m_nu = 0.06 eV) find H0=67.2+1.2-1.0 km/s/Mpc (68% CL). This result is completely independent of Hubble constant measurements based on the distance ladder, CMB anisotropies (both temperature and polarization), and strong lensing constraints. There are now 5 data sets that: a) have no shared observational systematics; and b) each constrain the Hubble constant with a few % level precision. Compare these 5 independent measurements, and find that, as a set, the difference between them are significant at the 2.1 sigma level (chi^2/dof=20.1/11, probability to exceed=4%). This difference is low enough that the data sets are considered statistically consistent with each other. The best fit Hubble constant obtained by combining all 5 data sets is H0=69.1+0.4-0.6 km/s/Mpc.
