Notes. Properties of 6 intermediate-mass black holes (IMBHs) ULXs observed in our simulations. Each IMBH forms multiple, short-lived ULX phases with different companions. Column definitions: label – simulation model name; t_phys,min – minimum ULX phase onset age (Gyr); t_phys,max – maximum age at which ULX phases occur (Gyr); M_min – minimum IMBH mass during ULX phases (1000 × M_⊙); M_max – maximum IMBH mass during ULX phases (1000 × M_⊙); duty-cycle – percentage of total IMBH lifetime spent in ULX phases; companions – types and numbers of donor stars (MS – main sequence, HG – Hertzsprung gap, RG – red giant, CHeB – core helium burning, EAGB – early asymptotic giant branch, TPAGB – thermally pulsating asymptotic giant branch, HeGB – helium giant branch, HeWD – helium white dwarf, COWD – carbon-oxygen white dwarf, ONeWD – oxygen-neon white dwarf).
