Galaxy and critical point distribution in the Coma supercluster in a ±75 Mpc redshift slice centred on the Coma cluster (marked with the red square). Small grey points represent the position of galaxies from the MGS. Large circles represent critical points colour-coded according to their type. Top panel: 3σ persistence threshold; bottom panel: 5σ persistence threshold. One-smoothing of the density field is applied prior to the filament and critical point detection. North is up, east is to the left.
