Extended Data Fig. 1: Distribution of galaxy morphologies as parameterized by B/D or B/T in the Sibelius simulation in the redshift range z = 0.01 − 0.04.

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

Extended Data Fig. 1

The blue curve shows galaxies in the stellar mass range 109 − 1010M⊙, the red curve shows galaxies above 1010M⊙, the grey dashed curve shows all galaxies above 109M⊙. There is a clear bimodality in the bulge fraction, and the fraction of galaxies with high bulge fraction increases with increasing stellar mass. The two vertical dotted lines denote B/D = 1/4 (B/T = 1/5), our default threshold separating disks and intermediates, and B/D = 8 (B/T = 8/9), our default threshold separating intermediates and ellipticals.
