Jet formation by flying black holes

Astrophysical jets are extended collimated outflows of ionized matter and magnetic fields that can accelerate to near light speeds. Particularly interesting are black hole jets. Most of their modeling has focused on static black holes. However, can moving black holes also power the jets? To model such systems, we have used HARMPI and H-AMR, codes that solve hyperbolic partial differential equations of general relativistic magnetohydrodynamics (GRMHD) on a curved black hole spacetime. We simulated jet formation for a black hole flying through a uniform gas threaded with magnetic fields at different inclinations, i.e., a magnetized version of Bondi-Hoyle-Lyttleton (BHL) accretion. We report on the dependence of jet power on the inclination angle of the magnetic field and the spin of the black hole.
