Map of the filaments connected directly to the Coma cluster in a ±75 Mpc redshift slice centred on Coma. Small grey points represent the galaxies from the MGS. Large points represent critical points colour-coded according to their type. Cyan lines represent filaments connecting critical points as detected by DisPerSE. Orange lines are first- and second-generation filaments (see text). Purple crosses are MCXC clusters, purple squares are groups and clusters from the Tempel et al. (2017) sample (with M200 ≥ 1014M), and small purple pentagons are SDSS supercluster member galaxies. The position of the Coma cluster is marked by a red square. The red dashed circle has a radius of 75 comoving Mpc and represents the projection of the sphere within which filaments connected to Coma were analysed. The top and bottom panels refer to 3σ and 5σ persistence thresholds, respectively. North is up and east is to the left.
