Drs. L. Kidder and S. Teukolsky will carry out research in numericalgravitation, and will develop new algorithms for supercomputersimulations of solutions to the Einstein Equations. The focus is totrack the coalescence and merger of binary black hole systems and tocalculate the gravitational waveform emitted by such processes. Theinvestigators will apply the computational technique of pseudospectralcollacation to this problem. The study of reliable waveforms is particularly timely.The theoretical solution of this problem is remarkably difficult.While the technique used in this study are new for this application, ithas proven successful in many other areas, and shows much promise forimproving computational efficiency in this area. The radiationprocesses under study are the primary target for gravitational wavedetectors, such as LIGO, currently under construction.
