项目摘要

This award funds theoretical research in several different topics in relativistic astrophysics and general relativity. One focus is the exploration of newly discovered conservation laws involving black holes, and their implications for deep and poorly understood issues in quantum gravity such as the information loss paradox discovered by Stephen Hawking. A second focus is on tests of general relativity and on sources of gravitational radiation that have been detected by the Laser Interferometer Gravitational Wave Observatory (LIGO) and that might be detected by future space based detectors. Theoretical studies of sources of gravitational waves funded by this award will be useful to aid detection of signals from black holes and other sources, and also to aid in their interpretation. Gravitational wave studies can tell us about the nature of gravity, properties of black holes, and properties of the early Universe.In more detail, the principal research topics of this award are: (i) The development of methods to compute the gravitational waveforms from point particles inspiralling into spinning black holes, using a combination of analytical and numerical approaches; (ii) Generalizing the mathematical formalism of Wald and Zoupas to develop a comprehensive description and understanding of conservation laws involving soft hair on black holes, and (iii) investigating the consequences of these laws for the quantum evaporation of black holes and the ultimate fate of information that falls into black holes.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项在相对论的天体物理学和一般相对论中为理论研究提供了理论研究。一个重点是探索涉及黑洞的新发现的保护法，及其对量子重力的深度和知识理解的意义，例如斯蒂芬·霍金（Stephen Hawking）发现的信息损失悖论。第二个重点是对一般相对论的测试和重力辐射的来源，这些辐射的来源已被激光干涉仪重力引力波观测站（LIGO）检测到，并且可以通过未来的基于空间的探测器检测到。该奖项资助的重力波源的理论研究将有助于辅助发现来自黑洞和其他来源的信号，并有助于其解释。引力波研究可以告诉我们重力的性质，黑洞的性质以及早期宇宙的性质。更详细的是，该奖项的主要研究主题是：（i）开发从分析和数字方法的组合，使用分析和数字方法组合，从点粒子中启发到旋转黑洞的点粒子的重力波形的发展；（ii）概括瓦尔德（Wald）和扎帕斯（Zoupas）的数学形式主义，以对涉及黑洞柔软头发的保护法的全面描述和理解，以及（iii）调查这些法律对黑洞的量子蒸发的后果，以及信息的最终命运，这些信息的最终命运属于黑洞，这些奖项落入黑洞中，这反映了NSF的智力和范围的范围。审查标准。
