Scientific paper

We present recently calculated waveforms from numerical relativity and their application to the search for and precision measurement of black hole binary coalescences using LISA. In particular, we focus on the advances made in moving beyond the equal mass, nonspinning case into other regions of parameter space, particularly the case of nonspinning holes with ever-increasing mass ratios as the state of the art has progressed. Also, we investigate the potential contribution from the merger portion of the waveform to measurement uncertainties of the binary's parameters. Until now, only the inspiral has been investigated due to the lack of availability of mergers and the increased complexity required in moving beyond the low frequency approximation of the interferometer, which is necessary when mergers are included. We discuss the subtleties of the problem, and present preliminary results.
