Description
Binary black holes can interact with surrounding matter, producing unique electromagnetic signatures and influencing their long-term evolution. Numerical simulations are crucial to understand the nonlinear behavior of gas and particles moving on this dynamical spacetime. We present a general binary black hole metric approximation valid at all binary separations for all practical purposes. We compare the metric against full numerical relativity in the context of General Relativistic Magnetohydrodynamical simulations. We show that the results are equivalent in many different scenarios, including merger and accretion from a circumbinary disk
