AdS perspective on the nonlinear tails in black hole ringdowns

Year: 2025

Type: article

Abstract: Black holes gradually settle into their static configuration by emitting gravitational waves, whose amplitudes diminish over time according to a power-law decay at fixed spatial locations. We show that the nonlinear tails in the presence of a quadratic source, which have been recently found to potentially dominate over the linear ones, can be simply derived from the AdS 2 × S 2 spacetime perspective with their amplitudes being related to the Aretakis constants.
