Evolution of the stellar 3D mass–half-mass radius relation for galaxies in our three runs (lines) against the observed relation at z = 0 (points) for galaxies of different morphological types. The simulations are shown by the solid blue (fiducial), magenta (ALL_Efb_e001_5ESN), and dashed light-blue (low star formation efficiency, weak feedback) lines. Observed galaxies are shown by points of the following type: the red pentagons and hexagons show a sample of elliptical and dwarf elliptical galaxies from the compilation of Misgeld & Hilker (2011); blue circles are the late-type galaxies from the samples of Leroy et al. (2008) and Zhang et al. (2012) with half-mass radii estimated from the deprojected surface density profiles, while the star symbol shows the Milky Way; the red cartwheel points show the Local Group dwarf spheroidal galaxies from the compilation of Misgeld & Hilker (2011). The light-blue dashed line and dot-dashed orange line show the average relations derived by Bernardi et al. (2014) for late- and early-type galaxies, respectively. The dark red shaded band shows ﹩2\sigma ﹩ scatter around the mean relation calculated for all galaxies in the Bernardi et al. (2014) sample. Individual galaxies from the SDSS, presented in Szomoru et al. (2013), are shown by dots.
