Velocity dispersion (σ_e) LOESS-smoothed distributions on the stellar mass–size plane for E-SDGs (left panel), E-DDGs (middle panel), and all galaxies (right panel) in the EAGLE simulation at z = 0. The median relations for the EAGLE galaxies (pink rhombus) are also shown. For comparison, the median relations for passive galaxies (left panel), active galaxies (middle panel), and all galaxies together (right panel) reported by van der Wel et al. (2014) are inside the black rhombus. Error bars correspond to the 16th and 84th percentiles for both simulated and observed data.
