Repellers in the local universe reconstructed from the CosmicFlows-4 galaxies (i.e identified in the peculiar velocity field reconstructed from the CF4 distances of galaxies). Overdensities are represented in different red shades by 3 levels of isosurfaces: 1, 1.4 and 1.75. Underdensities are highlighted in less transparent, blue shades and represented by 2 levels of isosurfaces: -1.27 and -1.6. Streamlines are derived by integrating the reconstructed peculiar velocity field in the backward direction (i.e integrating -1 x v). For the sake of clarity, extra noise has been removed by showing only streamlines part of basins of repulsion identified with the segmentation algorithm. Black spheres are located at the coordinates of repellers identified in the velocity field, i.e at the points where the streamlines are converging. The center of the reconstructed cube is located by the red, green and blue arrows of length 50 Mpc/h and directing along the supergalactic cartesian SGX, SGY and SGZ axes respectively.
