We present an analytical formalism, within the effective-one-body framework, which predicts gravitational-wave signals from inspiralling and coalescing black-hole binaries that agree, within numerical errors, with the results of the currently most accurate numerical-relativity simulations for several different mass ratios. In the equal-mass case, the gravitational-wave energy flux predicted by our formalism agrees, within numerical errors, with the most accurate numerical-relativity energy flux. We think that our formalism opens a realistic possibility of constructing a sufficiently accurate, large bank of gravitational-wave templates, as needed both for detection and data analysis of (nonspinning) coalescing binary black holes.

Templates for these waveforms are being constructed by matching the numerical results to post-Newtonian inspirals, for instance using the effective one-body approach [4, 5, 6, 7, 8], or purely phenomenological models [9, 10, 11, 12].
