On the connection between AGN radiative feedback and massive black hole spin

Understand

We present a novel implementation for active galactic nucleus (AGN) feedback through ultra-fast winds in the code gizmo.

• Our feedback recipe accounts for the angular dependence of radiative feedback upon black hole spin.
• We self-consistently evolve in time i) the gas accretion process from resolved scales to an unresolved AGN disc, ii) the evolution of the spin of the massive black hole (MBH), iii) the injection of AGN-driven winds into the resolved scales, and iv) the spin-induced anisotropy of the overall feedback process.
• We test our implementation by following the propagation of the wind-driven outflow into a homogeneous medium, and we compare the results against simple analytical models.
