Theoretical research in several different areas of gravitational wave astronomy, and also in areas of gravitation physics and relativistic astrophysics will be studied. The principal topics are: (A) theoretical simulations of the accuracy with which a network of gravitational wave detectors will be able to measure the distances to and masses of coalescing binary neutron stars, the most promising expected type of source; (B) investigations of how this accuracy will be improved by the construction, now being considered, of additional detector systems in Japan and/or Australia; (C) determining the required level of accuracy for theoretical template waveforms that will be used to analyze the experimental data; (D) developing new calculational tools that will be useful in future calculations of low frequency waves from supermassive black holes; (E) exploring quantitatively the prospects for measuring gravitational waves from distant black hole --- black hole mergers, both by ground based detectors and possible future space-based detectors; (F) an exploration of the effects of `anti-gravity` that occur when quantum fields are coupled to classical gravity, motivated by the expectation that this phenomenon will yield insight into the nature of quantum gravity; (G) theoretical explorations of the structure of a black hole's interior which probe deeply into the theoretical structure of general relativity and bring out its poorly-understood nonlinear features. In addition a comprehensive introductory course will be developed and taught at Cornell to graduate students and interested faculty, covering the various aspects of gravitational wave astronomy: the physical properties of the waves as predicted by general relativity, the experimental technology to detect them, the catalogue of anticipated sources, and the information we hope to extract from the waves about the nature of gravity, about cosmology, and about the various sources. The lecture notes will be made available on the world wide web so as to be accessible to a wide audience beyond Cornell. These web pages will be periodically updated to bring them up to date with the latest theoretical and experimental research in the field, thus tying the educational facility closely to current research. In summary, it is hoped that the course will contribute to curriculum development, foster interdisciplinary interactions, and disseminate specialized knowledge to a wide audience.

将研究引力波天文学的几个不同领域以及引力物理学和相对论天体物理学领域的理论研究。 主要议题是：（A）对引力波探测器网络将能够测量到合并中子星的距离和质量的精确度进行理论模拟，合并中子星是最有希望的预期源类型;（B）研究如何通过目前正在考虑的在日本和/或澳大利亚建造更多的探测器系统来提高这种精确度;（C）确定用于分析实验数据的理论模板波形所需的准确度;（D）开发新的计算工具，这将有助于未来计算超大质量黑洞的低频波;（E）通过地面探测器和未来可能的空间探测器，定量探索测量来自遥远黑洞-黑洞合并的引力波的前景;（F）探索量子场与经典引力耦合时出现的“反引力”效应，其动机是期望这种现象将使人们深入了解量子引力的性质;（G）黑洞内部结构的理论探索，深入探讨了广义相对论的理论结构，其不为人知的非线性特征。 此外，康奈尔大学还将为研究生和感兴趣的教师开发和教授一门全面的入门课程，涵盖引力波天文学的各个方面：广义相对论预测的波的物理性质，探测它们的实验技术，预期来源的目录，以及我们希望从波中提取的关于引力性质的信息，关于宇宙学，以及各种来源。 课堂讲稿将在万维网上提供，以便康奈尔大学以外的广大听众可以访问。 这些网页将定期更新，使其了解该领域最新的理论和实验研究，从而将教育设施与当前的研究紧密联系起来。 总之，我们希望该课程将有助于课程的发展，促进跨学科的互动，并传播专业知识，以广泛的受众。
