Webb Researchers Discover Lensed Supernova, Confirm Hubble Tension
On France Culture today: The Hubble Tension
... in an interview by the excellent Celine Loozen I talk about our Cosmicflows-4 measurement of the Hubble Constant, as well as the value inferred from Ho'oleilana, that are both exacerbating the tension.

Difference ways of measuring the Hubble Constant still don't agree with each other, yet.
"A long-awaited study of the cosmic expansion rate suggests that when it comes to the Hubble tension, cosmologists are still missing something."

‘Bubble’ of galaxies discovery may revolutionise cosmology
Cullan Howlett on the new measurement of the Hubble constant inferred from Ho'oleilana, in the press release by the University of Queensland: “We’re now a step closer to a great change in the field of cosmology, where the whole model of the universe might need re-evaluating.”
