# New analytic representation of the ringdown waveform of coalescing spinning black hole binaries

@article{Damour2014NewAR, title={New analytic representation of the ringdown waveform of coalescing spinning black hole binaries}, author={T. Damour and Alessandro Nagar}, journal={Physical Review D}, year={2014}, volume={90}, pages={024054} }

We propose a new way of analyzing, and analytically representing, the ringdown part of the gravitational wave signal emitted by coalescing black hole binaries.By contrast with the usual {\it linear} decomposition of the multipolar complex waveform $h(t)$ in a sum of quasi-normal modes, our procedure relies on a {\it multiplicative} decomposition of $h(t)$ as the product of the fundamental quasi-normal mode with a remaining time-dependent complex factor whose amplitude and phase are separately…
