#OxLancs2026

Preparing my talk for the 1st Ox & Lancs Colloquium on Cosmological Features on the Largest Scales at U. of Lancashire. Highlight of the meeting: a talk by Sir Roger Penrose (Nobel Prize 2020) on "Dark matter in Conformal Cyclic Cosmology and Lopez Galactic Rings".

look at this crazy metrics!

How amazing is that: Ho'oleilana ApJ paper has been downloaded 60000 times. Still ranking among the most read papers of this journal, and #openaccess

my favorite things

Mars, Encelade, the early universe (for a 10-pages zoom paper by yours truly on baryon acoustic oscillations, following the discovery of Ho'oleilana) are on the cover of the latest issue of l'Astronomie Magazine

how it started, how it's going

These are the 1st and latest covers of l'Astronomie, the venerable magazine established by Camille Flammarion in 1882. I'm honored to be the author of the feature article of this new issue, on Baryon Acoustic Oscillations.

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.
