From: Distinct distributions of elliptical and disk galaxies across the Local Supercluster as a ΛCDM prediction

Fig. 1

Hammer projection in supergalactic coordinates of the distribution of the most massive disks (left), intermediates (centre) and ellipticals (right) in the redshift range of 0.01 < z < 0.02, as reported in the 2MRS survey (top) and as modelled in SIBELIUS (bottom). The shaded areas correspond to \(\left\vert \sin ({{{\rm{SGB}}}})\right\vert < 0.2\) \(\left({{-11.{5}^{\circ }\leq{\rm{SGB}}}}\leq 11.{5}^{\circ }\right)\) around the supergalactic equator. Dark and light symbols show individual galaxies that lie inside and outside this region, respectively, and percentages in the top right of each panel express their relative numbers. Grey points denote lower mass galaxies (fainter for \(\left\vert b\right\vert < 1{0}^{\circ }\)) irrespective of morphology; labels indicate the positions of five galaxy clusters. In both the 2MRS data and the SIBELIUS simulation, a significantly higher fraction of massive ellipticals than of massive disks lie close to the supergalactic plane.
