Big H₀ paper out today: The “Local Distance Network” - a community consensus on the Hubble constant at 1% precision. This work started at a conference in Bern that invited experts across field to answer: how do we combine all the local H₀ measurements fairly? arxiv.org/abs/2510.23823

Lately, there have been different reports about the Hubble Tension from JWST, with different teams and methods. It’s been hard to follow. But initial sample sizes were small so in a new paper we combined, for the first time, all measurements to date, includes 5 JWST programs, and it makes a pretty clear picture. arxiv.org/abs/2408.11770 🧵

Next week seminar will be Wed 28th August at 4pm UK time with Adam Riess (Johns Hopkins University, US) talking about "What JWST Can and Cannot (yet) Reveal about the Hubble Tension”. Register here: cosmoversetensions.eu/for-scientists…

Busy week - new paper by George Efstathiou pointing out potential systematic uncertainties in the DES-5yr supernova analysis and its constraints on evolving dark energy. I have some thoughts, but wanted to start with a genuine appreciation of George. arxiv.org/abs/2408.07175

Istvan Szapudi’s seminar “The ISW Puzzle" is now online: youtu.be/O6EwfLDudyA

The US banned Hawaiian language, overthrew our country, let us die in Maui fires, devastated our universal healthcare, & illegally occupies Hawaii to this day. My mother's hands were broken for speaking Hawaiian in school. The US is not a beacon, but the destroyer of independence

Over 200 days of complicity, the EU waved Israel's flag & increased weapons exports tenfold. So spare us crocodile tears now. It could not have happened without EU complicity. It is continuing now because of it. European values? Same as they always were: Murder & colonialism.

We've been warning for months: US/EU support for Israel risks wider war. 6 months of genocide. Constant attacks on neighbours to provoke war, incl. Iran's consulate. Total impunity. No restraints. No consequences. That's why this is happening. To avert war, stop helping cause it.

These might not be the markers we need right now, but they are the ones we deserve arxiv.org/abs/2403.20314 kudos @NicoBorghi & co (and yes, this is real!)

Happening tomorrow morning! Join the mailing list!👇

Do you, like Fritz Zwicky, discoverer of dark matter, have people in your life known as "spherical bastards", because, as Zwicky said, they were bastards no matter which way one looked at them.

Our next seminar will be Wed 22nd November at 4pm UK time (unusual time!). Register here: cosmoversetensions.eu/for-scientists… to listen to Adam Riess (Johns Hopkins University, USA) talking about "Thanks (giving) for JWST".

Postdoc opportunity in cosmology at Sheffield to work on cosmological tensions! Deadline Nov 28 inspirehep.net/jobs/2716202
