WebWe compare a recently derived, resummed high post-Newtonian accuracy Effective-One-Body (EOB) quadrupolar waveform to the results of a numerical simulation of the inspiral and merger of an equal-mass black hole binary. We find a remarkable agreement, both in phase and in amplitude, with a maximal dephasing which can be reduced below ±0.005 … Webtional cost. The effective-one-body (EOB) formalism was introduced as a way to analytically describe the inspiral, merger, and ringdown waves emitted by comparable-mass BH binaries [3,4]. This formalism was then extended to higher post-Newtonian (PN) orders [5], spinning BHs [6– 8], small mass-ratio mergers [9,10], and was further im-
