New Paper: Turbulent accretion onto black holes

Last week, our paper (arXiv), led by KwangHo Park, on the behavior of accretion flows onto intermediate mass black holes was submitted to the Astrophysical Journal. Here we used 3D radiation hydrodynamics simulations to study how the surrounding environment is affected by radiation feedback that originates from the gas around the black hole. We found that the accretion rates are oscillatory in nature, agreeing with previous 1D and 2D simulations, but these bursts induce turbulence, which can enhance black hole growth rates during quiescent phases. Although turbulent energy does not dominate the energy budget, it plays a key role in the regulation of black hole fueling.
