Simulations of Supermassive Binary Black Hole: Accretion Dynamics in the Spinning case*

In recent years, numerical methods have been used to model supermassive black hole binaries with the purpose of identifying the properties and signatures of these systems. Here we present 3D-MHD simulations of spinning binary black holes with the use of the multi-mesh/multi-physics code PatchworkMHD, capable of evolving different physical regions with different mesh topologies. This new infrastructure has allowed to accurately resolve complicated system such as supermassive black holes surrounded by a circumbinary disk. With a new prescription of a dynamic spacetime, and trajectories for spinning black hole binary, we present new simulations showing the influence of the spin in binary environment, including the formation of mini-disks and jets.
