Attractors in the local universe reconstructed from the CF4 galaxies (top panel) and groups (bottom panel). The reconstructed overdensity field is represented by four levels of isosurfaces from white to dark red: 0.75, 1, 1.4, and 1.75 for CF4 galaxies, and 0.5, 0.8, 1.2, and 1.5 for CF4 groups. Streamlines were derived by integrating the reconstructed peculiar velocity field in the forward direction. For clarity purposes, extra noise has been removed by only showing streamlines part of basins of attraction identified with the segmentation algorithm, listed in the top part of Table A.1. Black spheres are located at the coordinates of attractors identified in the velocity field (i.e., at the points where the streamlines converge). The center of the reconstructed cube is indicated by the red, green, and blue arrows of length 50 Mpc h⁻¹ directing along the supergalactic cartesian SGX, SGY, and SGZ axes, respectively. Sketchfab interactive visualizations are available for both analyses (i.e., https://skfb.ly/oL976 and https://skfb.ly/oL977).
