Tip of the Red Giant Branch Distances with JWST. II. I-band Measurements in a Sample of Hosts of 10 Type Ia Supernova Match HST Cepheids

Tip of the Red Giant Branch Distances with JWST. II. I-band Measurements in a Sample of Hosts of 10 Type Ia Supernova Match HST Cepheids

The Hubble Tension, a >5 σ discrepancy between direct and indirect measurements of the Hubble constant ( H _0 ), has persisted for a decade and motivated intense scrutiny of the paths used to infer H _0 . Comparing independently derived distances for a set of galaxies with different standard cand...
