Charged examples of these objects exhibit an internal boundary named for Cauchy and satisfy the Reissner-Nordstrom metric. A photon sphere can occur near one of these, and the Penrose process seeks to extract energy from their ergospheres. The Lense-Thirring effect describes the frame-dragging produced by a rotating one of these objects subject to the no-hair theorem. Spontaneous pair production results in their emission of Hawking radiation, and the Schwarzchild radius is the distance from the center at which the event horizon occurs. Found at the center of galaxies, for 10 points, name these gravitational singularities from which nothing can escape.
