Analytic estimates using a validated Fokker-Planck and runaway-collision framework predict IMBH masses of 100-4000 solar masses in JWST-observed high-redshift clusters, with higher values in compact low-metallicity systems.
N-body simulations of ultra-faint dwarf galaxies without dark matter find a 3-billion-year quasi-stationary phase followed by mass segregation, with binaries causing substantial overestimates of velocity dispersion.
Simulations indicate stellar collisions dominate intermediate-mass black hole formation across cluster types, with potential to explain local globular cluster candidates and predict wandering IMBHs in Milky Way-like galaxies.
Direct N-body simulations independently confirm that preferential ejection of enriched RGB stars by an active black hole subsystem produces a transient overconcentration of pristine RGB stars in globular clusters that have lost substantial mass.
