Comparison and contrast of test-particle and numerical-relativity waveform templates [HEAP]

http://arxiv.org/abs/1706.07704


We compare and contrast the emission of gravitational waves and waveforms for the recently established “helicoidal-drifting-sequence” of a test particle around a Kerr black hole with the publicly available waveform templates of numerical-relativity. The merger of two black holes of comparable mass are considered. We outline a final smooth merging of the test particle into the final Kerr black hole. We find a surprising and unexpected agreement between the two treatments if we adopt for the mass of the particle and for the spin of the Kerr black hole, respectively, the Newtonian-center-of-mass description and the spin of the Kerr black hole formed in the merger.
