Cosmicflows-3: The South Pole Wall
  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.
