Illustration of a possible explanation of the breaks of the density profiles of GC systems in the ΛCDM framework proposed in the text. The solid line shows the gravitational potential of NGC 3115 obtained by fitting the GC kinematics (Bílek et al. 2019). The vertical dashed line marks the observed break radius of the GC system that virtually matches the r_sh radius. A similar explanation works for MOND as well, but the break occurs at the radius r_acc. The potential is given in arbitrary units.
