Understanding the Nature of Scalar-Induced Gravitational Waves
A. J. Iovino, G. Perna, D. Perrone +2
We offer a physical interpretation of the origin of the scalar-induced gravitational wave background, showing that it is mainly produced around the peaks of the scalar perturbation…

Nonlinearities in Kerr Black Hole Ringdown from the Penrose Limit
D. Perrone, A. Kehagias, A. Riotto
We provide a fully analytical approach to calculate the nonlinearities of the gravitational waves in the ringdown of a Kerr black hole in the eikonal limit. The corresponding quasi…
