∼30 Mpc-thick XY supergalactic slice of the CLONE. Black dots stand for the dark matter halos (subhalos are excluded for clarity). Red dots are galaxies and groups from the grouped 2MRS catalog for comparison purposes only (compressed Fingers-of-God from Tempel et al. 2018). Indeed, only a small fraction of local galaxy observational redshifts have been used to derive peculiar velocities that were used as constraints (about ∼2.5% of the 2MRS catalog). Red dot sizes are proportional to the richness of the groups. Observed groups (large red dots) are on top of simulated dark matter halos (black dots). No large red dot appears to be overlaid on the middle of a simulated void.
