"Structures cosmiques : une famille de géantes"

I was yesterday on France Culture to talk about the discovery of the Quipu Supercluster and other large scale structures.

Wow 98,000 peculiar velocities

The DESI DR1 Peculiar Velocity Survey: Fundamental Plane Catalogue
by C.E. Ross and co-authors
https://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

#OTD 2020, publication of the discovery of the South Pole Wall. This 1.4 billion light-years wide filament was detected through the gravitational influence it exerts on nearby galaxies, for which we measured distance and velocity.

Pleased to give a talk (online) to the Cosmology group at Observatório Nacional in Rio de Janeiro. After a short historical intro - discussing the role of pioneers such as Vera Rubin and Gérard de Vaucouleurs - I will present the discoveries of our Cosmicflows research program.

Hot from Wikipedia

Ho'oleilana enters the List of largest cosmic structures: https://en.wikipedia.org/wiki/List_of_largest_cosmic_structures

This list also account for two other of our past Cosmicflows findings: Laniakea and the South Pole Wall.
