Time evolution of the mass; half-light radius, r_50%; and filling factor, r_50%/r_j, of our set of simulations. Orange crosses are the initial conditions, blue dots are the snapshots at 12 Gyr, and the gray lines indicate the time evolution. The comparison with MW GCs (gray dots, Baumgardt GCs Database) highlights that our simulated GCs cover the current parameter space of real GCs in the low-density regime.
