Evolution of the cluster in a simulation with speed of light c = 10³ km/s and an external potential of η_g = 1.0. The first two panels on the left present the results of our fit considering a King’s model. In the top left panel, we display the density of the core, while in the second panel from the left at the top, we illustrate the core radius of the cluster. In the bottom left panel, we show the Lagrangian radius for mass fractions between 1% and 90% of the total mass of the cluster. The top right panel shows the mergers of BHs in the cluster in bins of 5 Myr. In the middle right panel we show the growth in the mass of the most massive BH in the cluster. The bottom right panel shows the accumulative ejections in the cluster. The vertical line in the panels corresponds to the moment when the highest central density is reached.
