This award supports the study of computer simulations of black holes in orbit with each other or with neutron stars. More specifically, computer codes will be developed to construct numerical solutions to Einstein's equations of General Relativity. The emphasis of this project will be to explore methods and algorithms for the initial data for isolated black holes or black holes in orbit that will lead to models of orbiting black holes that are more realistic than those that are currently available.Understanding black holes in binary systems is important for our understanding of gravity, one of the four fundamental forces of nature. In more practical terms, accurate models of orbiting black holes are crucial for data analysis in the NSF-funded Laser Interferometer Gravitational-Wave Observatory (LIGO), designed to detect gravitational radiation emitted by such systems. This award also supports undergraduate students who are actively involved in this research, and who receive valuable training preparing them for future careers in the sciences and beyond.

该奖项支持对相互之间或与中子星在轨道上的黑洞进行计算机模拟的研究。更具体地说，将开发计算机代码来构建爱因斯坦广义相对论方程的数值解。这个项目的重点将是探索孤立黑洞或轨道上黑洞的初始数据的方法和算法，这些方法和算法将导致比目前可用的模型更真实的黑洞轨道模型。了解双星系统中的黑洞对于我们理解四种基本自然力之一的引力是很重要的。更实用的说法是，在美国国家科学基金会资助的激光干涉仪引力波天文台(LIGO)的数据分析中，围绕黑洞运行的准确模型至关重要，该天文台旨在探测此类系统发出的引力辐射。该奖项还支持积极参与这项研究的本科生，并接受了宝贵的培训，为他们未来在科学和其他领域的职业生涯做准备。
