Kinetic AGN Feedback Effects on Cluster Cool Cores Simulated using SPH

Understand

We implement novel numerical models of AGN feedback in the SPH code GADGET-3, where the energy from a supermassive black hole (BH) is coupled to the surrounding gas in the kinetic form.

• Gas particles lying inside a bi-conical volume around the BH are imparted a one-time velocity (10,000 km/s) increment.
• We perform hydrodynamical simulations of isolated cluster (total mass 10^14 /h M_sun), which is initially evolved to form a dense cool core, having central T<10^6 K.
• A BH resides at the cluster center, and ejects energy.
