Abstract

We numerically compute the ringdown amplitudes following the plunge of a particle from the innermost stable circular orbit of a Schwarzschild black hole in the extreme-mass ratio limit. We show that the ringdown amplitudes computed in this way are in good agreement with a recent analytical calculation.
