9417348 Thorne This award supports a two-year cooperative research project between Dr. Kip Thorne of the California Institute of Technology and Professor Takashi Nakamura of Kyoto University. This research is in support of the LIGO (Laser Interferometer Gravitational-Wave Observatory) Project and of the corresponding interferometric gravitational-wave-detection project in Japan: theorists need to compute, from general relativity, the gravitational waveforms produced by such binaries for use as templates in the analysis of the interferometer data. The Caltech group has great expertise in what types of calculations need to be done and how to relate the results of those calculations to the planned observations; Caltech also has moderate expertise in the calculational techniques. The Kyoto group has greater expertise and experience than the Caltech group in two of the principal calculational techniques: the theory of perturbations of massive black holes, and numerical simulations of the final coalescence. By combining these expertises, the two groups can achieve a deeper understanding and more rapid progress than can either group alone. ***

小行星9417348 该奖项支持加州理工学院的Kip Thorne博士和京都大学的Takashi中村教授之间为期两年的合作研究项目。 这项研究是为了支持LIGO（激光干涉引力波天文台）项目和日本相应的干涉引力波探测项目： 理论家需要从广义相对论中计算出这类双星产生的引力波形，作为分析干涉仪数据的模板。 加州理工学院的团队在需要进行哪些类型的计算以及如何将这些计算的结果与计划的观测相关联方面具有很强的专业知识;加州理工学院在计算技术方面也具有中等的专业知识。 京都小组在两个主要的计算技术上比加州理工学院小组有更丰富的专业知识和经验：大质量黑洞的扰动理论和最终合并的数值模拟。 通过结合这些专业知识，这两个小组可以实现更深入的理解和更快的进展比任何一组单独。 ***
