The Blandford-Znajek process can only occur in this area, and plasmas in this region will generate Alfven waves that emit energy outward via the Poynting flux. Superradiance is the spontaneous emission of positive-energy photons in this region, and, under certain conditions, negative phase velocity propagation can occur here. One interpetation of this defines it as the area in which it is impossible for a particle to move on an integral curve of a Killing vector. Small relativistic jets can form in this area since it is undergoing the Lense-Thirring effect, and it only exists when a Kerr metric is present. Penrose processes take place in, for 10 points, what ellipsoid region outside of a black hole from which energy and mass can be extracted?
