    The Magnetic Lives of Black Holes and Neutron Stars

    The most extreme and surprising behaviors of black holes and neutron stars are driven by their surrounding plasmas and magnetic fields. Numerical simulations which capture basic physical processes like particle acceleration, magnetic reconnection, and magneto-rotational turbulence can yield insight into such disparate phenomena as black-hole jets and X-ray coronae, magnetar giant gamma-ray flares, and the spin limit of millisecond pulsars. I will focus on what simulations can teach us about the launching of relativistic jets in compact binary mergers, and will describe how a new technique for general-relativistic plasma kinetics will aid in understanding black holes' jets and particle acceleration, and in interpreting future observations with the Earth-spanning Event Horizon Telescope.
