Fig. 5: Distributions of galaxies beyond z = 0.02.

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

Fig. 5

Hammer projection in supergalactic coordinates of the distributions of the most massive disks (blue) and ellipticals (red) in 2MRS (top) and SIBELIUS (bottom) in three redshift slices. Galaxies are selected at ∣b∣ > 10° and with masses similar to the 100 most massive galaxies of each type for z in the range 0.01–0.02. As in Fig. 1, dark and faint circles denote galaxies within and outside ±11.5° of the supergalactic plane, respectively. Fainter galaxies are shown in grey. The percentages in the top right of each panel express the fraction of galaxies in each class that are within ±11.5° of the supergalactic plane. The ellipticals more closely trace the distribution of the most prominent structures, while the disks are more equally distributed. The excess of galaxies at low supergalactic latitudes extends to z ≈ 0.025. At higher redshifts, the distributions of both structures and galaxies are no longer aligned with the supergalactic plane.
