Daniel Pomarede, R. Brent Tully, Romain Graziani, Helene M. Courtois,, Y. Hoffman, Jeremy Lezmy

TL;DR
This paper reports the discovery of the South Pole Wall, a massive filamentary structure in the local universe identified through velocity and density field reconstructions from the Cosmicflows-3 galaxy distance catalog.
Contribution
It introduces the South Pole Wall as the largest contiguous structure in the local volume, identified using new velocity and density reconstructions from Cosmicflows-3 data.
Findings
Discovery of the South Pole Wall as a major filamentary structure.
The structure extends across approximately 0.11c.
It is comparable in size to the Sloan Great Wall at half the distance.
Abstract
Velocity and density field reconstructions of the volume of the universe within 0.05c derived from the Cosmicflows-3 catalog of galaxy distances has revealed the presence of a filamentary structure extending across ~ 0.11c. The structure, at a characteristic redshift of 12,000 km/s, has a density peak coincident with the celestial South Pole. This structure, the largest contiguous feature in the local volume and comparable to the Sloan Great Wall at half the distance, is given the name the South Pole Wall.
