Properties of ATLAS^3D host galaxies and their TNG50 analogues. Left: luminosity functions of TNG50 and ATLAS^3D hosts are plotted in solid and dotted lines, respectively. The latter corresponds to Fig. 3 in Cappellari et al. (2011). Samples containing only early-type and late-type centrals are denoted in red and blue respectively. Middle: mass distribution of the dark matter halos hosting the TNG50 analogues. Right: distance distribution of ATLAS^3D targets, smoothened via a Gaussian kernel for re-sampling in this work. The MATLAS survey targets a subset of the early-type ATLAS^3D hosts (solid red line).
