Gravity Waves from Extreme-Mass-Ratio Plunges into Kerr Black Holes

Understand

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 shown to be related by a conformal map to a circular orbit.
• Conformal symmetry of the near-horizon region is then used to compute the gravitational radiation produced during the plunge phase.
