Fornax Eridanus supercluster. The grey line traces the 2D projection of the filaments that form the Fornax Wall spine (R24). Green circles and their corresponding labels represent the Fornax Wall groups (R24, Tempel et al. 2016) and their virial radii (Kourkchi & Tully 2017). Grey points are the brightest galaxies in clusters and in groups. The Eridanus supergroup, Fornax cluster, and the Dorado group are highlighted with different colours. The dotted line is the DES footprint of T21 and T24, which encloses nearly all of the Fornax Wall.
