Radiative AGN feedback on a moving mesh: the impact of the galactic disc and dust physics on outflow properties

Understand

Feedback from accreting supermassive black holes, active galactic nuclei (AGN), is now a cornerstone of galaxy formation models.

• In this work, we present radiation-hydrodynamic simulations of radiative AGN feedback using the novel Arepo-RT.
• A central black hole emits radiation at a constant luminosity and drives an outflow via radiation pressure on dust grains.
• Utilising an isolated NFW halo we validate our setup in the single and multi-scattering regimes, with the simulated shock front propagation in excellent agreement with the expected analytic result.
