New results from TDCOSMO on the Hubble tension. They find H0 = 71.1 (+2.4, -2.3) km\/s\/Mpc (3.3% precision) from 11 time-delay gravitational lenses, now accounting for the mass-sheet degeneracy.<\/p>\n\n\n\n
The result is independent of the local distance ladder and remains essentially unchanged when supernova data are excluded entirely.<\/p>\n\n\n\n
While the baseline TDCOSMO result differs from Planck by 1.6\u03c3, combining TDCOSMO with other independent late-time probes yields a 3.7\u03c3 Hubble tension without using supernovae, or 2.7\u03c3 when excluding the entire local distance ladder.<\/p>\n\n\n\n
The Hubble tension therefore persists independently of SH0ES and supernova-based measurements, with the new TDCOSMO results providing further support for a higher H0.<\/p>\n\n\n\n
