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.
