Eccentric binary black-hole mergers: The transition from inspiral to plunge in general relativity

U. Sperhake, E. Berti, V. Cardoso +3

We study the transition from inspiral to plunge in general relativity by computing gravitational waveforms of non-spinning, equal-mass black-hole binaries. We consider three sequen…
