Distribution of galaxies. From top to bottom: in the raw, corrected, ten stacked realization third catalog of the Cosmicflows project in the three supergalactic 40 h⁻¹ Mpc thick slices (from left to right). Blue circles stand for galaxies with negative peculiar velocities. Red filled circles represent galaxies with positive peculiar velocities. The strong biases affecting the raw catalog (top) is clearly visible with negative velocities at large distances. The filamentary structure of the cosmic web is visible in the corrected catalogs.
