Figure showing the relation between t₉₀ and stellar mass, as presented in Paper IV. The orange diamonds are dwarf galaxy satellites of the Milky Way or Andromeda; these galaxies are included in the plot simply to show how the U-shape continues for less massive galaxies. The red circles are the dwarfs from the SAMI-Fornax sample. The giant galaxies from the ATLAS^3D project are represented by empty or filled black dots depending on whether they are in the field or a cluster, respectively. In addition to the figure in Paper IV, we have added the Fornax3D galaxies as red triangles. For all the observed galaxies, we include the mass-binned mean of t₉₀ with a dashed grey line and a grey shadow shows the standard deviation. The simulated galaxies from IllustrisTNG (https://www.tng-project.org/) are the cyan points, while the blue line is the mass-binned mean of these galaxies.
