Recently, it has been shown that with the inclusion of overtones, the post-merger gravitational waveform at infinity of a binary black hole system is well-modelled using pure linear theory. However, given that a binary black hole merger is expected to be highly non-linear, where do these non-linearities, which do not make it out to infinity, go? We visualize quantities measuring non-linearity in the strong-field region of a numerical relativity binary black hole merger in order to begin to answer this question.

Self-force framework for merger-ringdown waveforms
A phase-space self-force framework is extended through the final plunge to produce merger-ringdown waveforms at leading geodesic order, with stationary-phase and quasinormal-mode approximations both failing near the p...

Quasinormal mode content of binary black hole ringdowns
A Bayesian, evidence-based analysis of 13 simulated black-hole ringdowns tabulates which quasinormal overtones, retrograde modes, and nonlinear (quadratic and cubic) modes are present at each start time, and finds no ...

The impact of initial conditions on quasi-normal modes
Using an exactly solvable delta-function potential, the authors show linear quasi-normal mode amplitudes are generically time-dependent and derive stabilization times that can greatly exceed the usual 10 solar mass ru...
