Dependence of BH accretion on initial conditions of BHs. From our high-resolution fiducial simulations, we mark BHs with resolved accretion in a phase space of the accreted mass (ΔM_BH) versus the initial mass ($M_{\mathrm{BH}}^{\mathrm{ini}}$), distance to the cloud’s center ($r_{\mathrm{BH}}^{\mathrm{ini}}$), velocity ($v_{\mathrm{BH}}^{\mathrm{ini}}$), and specific angular momentum ($j_{\mathrm{BH}}^{\mathrm{ini}}$). We find only a weak dependence on these initial conditions. We may also clearly see the mass-resolution limit from the lower “cutoff” in ΔM_BH for the 10⁸ M_⊙ complex.
