Zwicky Transient Facility’s 772 Type Ia supernovae yield H0 ≈ 72 km/s/Mpc, reinforcing local measurements

A 772-supernova sample from ZTF yields H0 ≈ 71.6–72.3 km/s/Mpc, supporting higher local measurements and deepening the Hubble-tension debate.

Reanalysis with Corrected Pantheon+ and DES-DOVEKIE Leaves Hubble Tension Intact

A reanalysis applying corrected Pantheon+ and DES-DOVEKIE supernova data finds the local Hubble constant stays near 73 km/s/Mpc, leaving the Hubble tension unchanged.

Updated Pantheon+ and DES Supernova Data Leave Local Hubble Constant Near 73, Study Finds

An arXiv preprint finds corrected Pantheon+ and DES-DOVEKIE supernova data keep the local Hubble constant near 73 km/s/Mpc, leaving the Hubble tension intact.
