U.S.-Japan Cooperative Research: Gravitational Waves from Coalescing Compact Binaries

9417348索恩该奖项支持加州理工学院的基普·索恩博士和京都大学的中村隆教授之间为期两年的合作研究项目。这项研究支持LIGO(激光干涉仪引力波天文台)项目和日本相应的干涉引力波探测项目：理论家需要根据广义相对论计算这类双星产生的引力波形，以用作干涉仪数据分析的模板。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中的观测相关联方面拥有丰富的专业知识；加州理工学院在计算技术方面也拥有中等专业知识。京都小组在两项主要的计算技术方面比加州理工小组拥有更多的专业知识和经验：大质量黑洞的微扰理论，以及最终合并的数值模拟。通过将这些专业知识结合起来，两组人可以比任何一组人单独获得更深的理解和更快的进步。***

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. ***
