The Cold-Spot Repeller

sketchfab

The Cosmicflows-3 catalog of galaxies peculiar velocities yields a Wiener Filter reconstruction of the gravitational potential field and flow. A dark grey polygon marks the surface where the potential field's value is consistently negative (-580). In contrast, a light blue polygon represents the surface with symmetric positive values (+580). Flow lines originating from the negative surface are colored red when they are seeded in the Dipole Repeller, while those seeded in the Cold-Spot Repeller remain black. Annotations 1 and 3 pinpoint the locations of the Cold-Spot and Dipole repellers where flow diverges. The positions of attractors, where flow converges, are indicated by annotations 2, 4, and 5. Annotation 6 marks the location of the Milky Way. The box's width spans 128,000 km/s. A central signpost features arrows, each measuring 10,000 km/s in length, pointing to SGX (red), SGY (green), and SGZ (blue) directions within the Supergalactic Coordinate System. The yellow arrow indicates the direction of the CMB Dipole apex, while a black arrow points towards the CMB Cold Spot.
