Massive objects orbiting a near-extreme Kerr black hole quickly plunge into the horizon after passing the innermost stable circular orbit. The plunge trajectory is related by a conformal map to a circular orbit. Conformal symmetry of the near-horizon region can then be used to analytically compute the gravitational radiation produced during the plunge phase.
