This award funds theoretical research in several different topics in relativistic astrophysics and general relativity, with a focus on sources of gravitational radiation that might be detected by the Laser Interferometer Gravitational Wave Observatory (LIGO) and by the proposed space based detector, the Laser Interferometer Space Antenna (LISA). The principal topics are: (i) the development of methods to compute the gravitational waveforms from point particles inspiralling into spinning black holes; (ii) the development of theoretical tools for studying tidal interactions of objects with relativistic gravitational fields; (iii) the exploration of properties of black holes in theories with branes and extra dimensions; and (iv) the computation of experimental and theoretical constraints on various alternative theories of gravity that have been proposed as models of the Universe's acceleration.The work on development of computational methods for gravitational waveforms will eventually have a significant impact on gravitational wave astronomy, by facilitating the detection and analysis of gravitational wave signals, from which we can learn about properties of black holes. Education and training of graduate and undergraduate students will be integrated into the research program.

该奖项资助相对论天体物理学和广义相对论中几个不同主题的理论研究，重点是激光干涉仪引力波天文台(LIGO)和拟议的天基探测器--激光干涉仪空间天线(LISA)可能探测到的引力辐射源。主要的主题是：(I)计算激发进入旋转黑洞的点粒子的引力波形的方法的发展；(Ii)研究物体与相对论引力场的潮汐相互作用的理论工具的发展；(Iii)在有膜和额外维度的理论中探索黑洞的性质；以及(Iv)对作为宇宙加速模型的各种替代引力理论的实验和理论约束的计算。引力波形计算方法的发展工作最终将对引力波天文学产生重大影响，因为它有助于探测和分析引力波信号，从中我们可以了解黑洞的性质。研究生和本科生的教育和培训将纳入研究计划。
