• W2150240972 abstract "The observational evidence that Super-Massive Black Holes (M• ∼ 109–10 M⊙) are already in place less than 1 Gyr after the big bang poses stringent time constraints on the growth efficiency of their seeds. Among proposed possibilities, the formation of massive (∼103–6 M⊙) seeds and/or the occurrence of super-Eddington (⁠|$dot{M}>dot{M}_{{rm Edd}}$|⁠) accretion episodes may contribute to the solution of this problem. In this work, using a set of astrophysically motivated initial conditions, we analytically and numerically investigate the accretion flow on to high-redshift (z ∼ 10) black holes to understand the physical requirements favouring rapid and efficient growth. Our model identifies a ‘feeding-dominated’ accretion regime and a ‘feedback-limited’ one, the latter being characterized by intermittent (duty cycles |${cal D} lesssim 0.5$|⁠) and inefficient growth, with recurring outflow episodes. We find that low-mass seeds (≲103–4 M⊙) evolve in the feedback-limited regime, while more massive seeds (≳105–6 M⊙) grow very rapidly as they are found in the feeding-dominated regime. In addition to the standard accretion model with a fixed matter–energy conversion factor (ϵ = 0.1), we have also explored slim disc models, appropriate for super-Eddington accretion, where radiation is trapped in the disc and the radiative efficiency is reduced (ϵ ≲ 0.04), which may ensure a continuous growth with |$dot{M} gg dot{M}_{{rm Edd}}$| (up to |${sim } 300,dot{M}_{{rm Edd}}$| in our simulations). Under these conditions, outflows play a negligible role and a black hole can accrete 80–100 per cent of the gas mass of the host halo (∼107 M⊙) in ∼10 Myr, while in feedback-limited systems we predict that black holes can accrete only up to ∼15 per cent of the available mass." @default.
