Evolution of the normalized accretion rate ṁ ≡ Ṁ_acc/Ṁ_Edd for the isolated 10¹¹ M_⊙ halo, assuming that a M_BH = 10⁶ M_⊙ were present. The BHL and floor accretion rates are shown in blue and green respectively and the Eddington limit by the dotted line at 1. There is enough mass available for accretion thanks to the high density present in the central region at the start, which allows for both the BHL and floor accretion rates to be above the limit.
