Gravity Waves from Extreme-Mass-Ratio Plunges into Kerr Black Holes
Shahar Hadar, Achilleas P. Porfyriadis, Andrew Strominger
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 rela…

Effective Action, Boundary Conditions, and Virasoro Algebra for AdS
Achilleas P. Porfyriadis, Frank Wilczek
We construct, to second order, the effective action of General Relativity for small excitations generated by a vector field and use it to study conformal symmetry in the boundary o…
