GCs hosting an IMBH at z = 0, compared to observed host candidates in local GCs (squares; Lützgendorf et al. 2013b) and a potential TDE (right triangle; Lin et al. 2018), for two sets of initial mass–half-mass radius conditions. The orange-edged star marks the ω Cen cluster (Häberle et al. 2024). As in Fig. 3, the dashed lines correspond to mass ratios M_IMBH/M_cl = 10⁻¹, 10⁻², 10⁻³. The top panel shows the results from a B-POP simulation of 10⁸ GCs, while the bottom panel shows the results from a simulation in which the same GCs have initial masses higher by 0.5 dex and half-mass radii smaller by 1 dex.
