INT-0242507LehnerThis award supports a three-year collaborative research project between Professor Luis Lehner (LSU), and Professor Nigel T. Bishop (University of South Africa). The investigators will collaborate on research for the simulation of binary systems containing: [a] black hole and a star and [b] a supermassive black hole and a star . The USA side will contribute with its expertise on the needed simulations and computational facilities while the South African side its expertise on algebraic manipulation. Additionally, both sides have vast knowledge on the formalism and numerical techniques that will be employed in the project. The goal will be to predict the expected gravitational wave emission produced by these systems. These two target systems are prime candidates to produce radiation, of gravitational origin, which highly sensitive detectors could measure (earth-based detectors in system [a], while spaced-based detectors for [b]). The prediction of the expected gravitational waves will be important for their detection and crucial for deciphering the information carried by them. Furthermore, the activities of this project will give new research opportunities to young researchers in both countries (and in particular to two junior investigators in South Africa at historically disadvantaged institutions). The project will introduce a new generation of scientists to multidisciplinary and collaborative research and enhance the participation of the South African partners in leading edge research in gravitational wave physics. This award is co-funded by NSF's Office of International Science and Engineering and by the Stellar Astronomy and Astrophysics Program, Division of Astronomical Sciences, Directorate of Mathematical and Physical Sciences.

Int-0242507Lehner该奖项支持Luis Lehner教授(路易斯安那州立大学)和Nigel T.Bishop教授(南非大学)之间为期三年的合作研究项目。研究人员将合作研究模拟包含：[a]黑洞和一颗恒星以及[b]一个超大质量黑洞和一颗恒星的双星系统。美国方面将利用其在所需的模拟和计算设施方面的专业知识作出贡献，而南非方面将以其在代数处理方面的专业知识作出贡献。此外，双方对将在该项目中使用的形式主义和数值技术都有丰富的知识。目标将是预测这些系统产生的预期引力波发射。这两个目标系统是产生高灵敏度探测器可以测量的引力源辐射的主要候选者(系统[a]中的陆基探测器，而[b]系统中的空间基探测器)。对预期引力波的预测对它们的探测将是重要的，对破译它们携带的信息至关重要。此外，该项目的活动将为两国的年轻研究人员(特别是南非历史上处于不利地位的机构的两名初级研究人员)提供新的研究机会。该项目将向新一代科学家介绍多学科和协作研究，并加强南非合作伙伴对引力波物理前沿研究的参与。该奖项由美国国家科学基金会国际科学与工程办公室和数学和物理科学局天文科学部恒星天文学和天体物理计划共同资助。
