"The Jet-Disk Boundary Layer"

Abstract:

Extragalactic radio jets were long thought to be powered by a dynamical process occurring close to a black hole, but the launching region was too small to be probed directly. Now, however, the Event Horizon Telescope has produced a resolved image of the black hole in M87, and in the future we may reasonably expect Event Horizon Telescope to produce time, space, and polarization resolved images of the jet base and surrounding accretion flow. I will review models of jet launching and describe some recent simulations that highlight the importance of the boundary between jet and disk in the region close to the black hole.
