Abstract

Abstract Velocity and density field reconstructions of the volume of the universe within 0.05 c derived from the Cosmicflows-3 catalog of galaxy distances has revealed the presence of a filamentary structure extending across ∼0.11 c . The structure, at a characteristic redshift of 12,000 km s −1 , 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.
