Wow 98,000 peculiar velocities
The DESI DR1 Peculiar Velocity Survey: Fundamental Plane Catalogue
by C.E. Ross and co-authors
arxiv.org/abs/2512.03226
For comparison: the Great Attractor was discovered with 400 PVs, Laniakea with 8000 PVs, South Pole Wall with 18,000 PVs

So on the one hand, maybe some small progress on the theory side making it easier to come up with models that can explain the data.
On the other hand, on the data side things are still moving with supernovae, and the evidence that there is something to explain is now a little bit weaker! 🧪🔭

The sonifications from of the COLIBRE simulations are incredible! They use strauss.readthedocs.io (from the folks at audiouniverse.org, @trayford.bsky.social) [no affiliation with me].

Great news that as a collaboration we in DESI have been awarded the Lancelot M. Berkeley-New York Community Trust prize for meritorious work in astronomy for 2026! The citation specifically references our two BAO cosmology papers, which are very close to my heart 💜

All supernovas ever observed, tens of thousands of dying stars
Once the Rubin Observatory is completed it will be able to see several millions of supernovas, dwarfing what we've seen so far
This is from a brilliant website by Isaac Shivvers.
