We numerically compute the ringdown amplitudes following the plunge of a particle from the innermost stable circular orbit (ISCO) 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 arXiv:0911.3899.

  1. Black hole mergers beyond general relativity: a self-force approach

    gr-qc 2025-10 unverdicted novelty 7.0 of 10

    Self-force theory is extended to compute merger and ringdown waveforms in beyond-GR black hole binaries under the extreme mass-ratio approximation, with first calculations of self-force corrections to the merger waveform.

  2. Gravitational waves in massive gravity: Waveforms generated by a particle plunging into a black hole and the excitation of quasinormal modes and quasibound states

    gr-qc 2024-11 reject novelty 6.0 of 10

    A plunging particle around a Schwarzschild black hole in massive gravity excites quasibound states, with a claimed harmonic resonance amplifying the even-parity dipole mode.
