Time evolution of galactocentric radius (upper panels) and bound mass (lower panels) of the globular cluster models in runs A1 and A2 (see Table 1). In the lower panels we show separately the bound mass in BHs (curve starting at 6 × 10⁴ M_☉) and in stars (curve starting at 1.1 × 10⁶ M_☉) Dashed curves in the upper panels give the galactocentric radii in the initial galaxy models containing 10⁴ and 10⁵ M_☉.
