How the super-Eddington regime regulates black hole growth in high-redshift galaxies

Understand

Super-Eddington accretion is one scenario that may explain the rapid assembly of $\sim 10^9\rm\, M_\odot$ supermassive black holes (BHs) within the first billion year of the Universe.

• This critical regime is associated with radiatively inefficient accretion and accompanied by powerful outflows in the form of winds and jets.
• By means of hydrodynamical simulations of BH evolution in an isolated galaxy and its host halo with 12 pc resolution, we investigate how super-Eddington feedback affects the mass growth of the BH.
• It is shown that super-Eddington feedback efficiently prevents BH growth within a few Myr.
