Recent progress in numerical relativity has enabled us to model the non-perturbative merger phase of the binary black-hole coalescence problem. Based on these results, we propose a phenomenological family of waveforms which can model the inspiral, merger and ring-down stages of black-hole coalescence. We also construct a template bank using this family of waveforms and discuss its implementation in the search for signatures of gravitational waves produced by black-hole coalescences in the data of ground-based interferometers. This template bank might enable us to extend the present inspiral searches to higher-mass binary black-hole systems, i.e., systems with total mass greater than about 80 solar masses, thereby increasing the reach of the current generation of ground-based detectors.

Notes on the integration of numerical relativity waveforms (2010, methodology): “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].”
Physics, Astrophysics and Cosmology with Gravitational Waves (2009, methodology): “This has been implemented with bar detectors [52] and between LIGO and the ALLEGRO bar detector [391].”
High-accuracy comparison of numerical relativity simulations with post-Newtonian expansions (2007, background): “Since then, an enormous amount of work has been done on the late inspiral and merger of black hole binaries, among them studies of the universality of the merger waveforms [14, 15], investigations into black hole kicks [11, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28] and spin dynamics [29, 3”
Black-hole binaries, gravitational waves, and numerical relativity (2010, methodology): “The “phenomenological” templates of Ajith et al. (2008, 2007) are simple three-segment curves in frequency space, with matching parameters tuned by numerical data generated by the BAM (Brügmann et al., 2008b) and CCATIE (Pollney et al., 2007) codes.”
