The Cold-Spot Repeller

sketchfab

Wiener Filter reconstruction of the gravitational potential field and flow obtained with the Cosmicflows-3 catalog of galaxies peculiar velocities. The dark grey polygon is a surface of constant negative value (-580) of the potential field. The light blue polygon is a surface of the symmetric positive value (+580). Flow lines are seeded in the negative surface, colored red where seeded in the Dipole Repeller, colored black where seeded in the Cold-Spot Repeller. Annotations 1 and 3 indicate the locations of the Cold-Spot and Dipole repellers where the flow diverge. Annotations 2, 4, and 5 indicate the position of the attractors where the flow converge. Annotation 6 indicate the position of the Milky Way. The box is 128,000 km/s-wide. The central signpost has 10,000 km/s-long arrows pointing to the SGX (red), SGY (green), SGZ (blue) directions of the Supergalactic Coordinate System. The yellow arrow indicates the direction of the CMB Dipole apex. The black arrow indicates the direction of the CMB Cold Spot.
