Detection of Gravitational Waves: Data Analysis, Detector Characterization, and Instrument Science for Advanced LIGO

开展先进引力波探测器的数据分析和仪器科学研究。将开发和实施用探测器网络对引力波爆发的相干搜索。特别注意中等质量的双黑洞合并和具有高偏心轨道的双星系统。将开发在线突发搜索，使联合引力波和电磁观测成为可能。随机搜索将产生随机中间数据，例如那些分析长时间瞬变的随机搜索。在仪器科学方面，将开展热自适应模式匹配、波束抖动抑制装置和改进波前传感的工作。展望未来，低温材料和设备的研究，包括用于测试质量的硅，将会发生。UF LIGO小组为学生和博士后科学家提供了从不同学科发展科学技能的机会，包括激光和光学，电子和反馈控制系统，真空和低温，计算方法，数据分析算法开发以及大型探测器调试和操作。佛罗里达大学LIGO小组非常重视本科生的教育，每年都有本科生参与研究。此外，该小组在UF LIGO实验室有很强的指导学生和博士后的传统；这些学生中的许多人已经继续接受引力波科学的进一步教育和职业生涯。这些努力将继续下去。这项工作将通过UF LIGO直接参与LIGO天文台的研究和运营，对国家和国际科学基础设施产生积极影响。最后，拟议的研究的影响超出了引力波科学。本项目研制的高功率光学器件在激光和光学工业中具有商业应用价值。

Data analysis and instrument science research for advanced gravitational-wave detectors will be carried out. Coherent searches for gravitational-wave bursts with networks of detectors will be developed and implemented. Special attention is given to intermediate-mass binary black hole mergers and to binary systems with highly eccentric orbits. Online burst searches, which enable joint gravitational-wave and electromagnetic observations, will be developed. Stochastic intermediate data will be generated for stochastic searches, such as those analyzing long duration transients. In instrument science, work on thermal adaptive mode-matching, devices for beam-jitter suppression, and improved wavefront sensing will be carried out. Looking further into the future, studies of cryogenic materials and devices, including silicon for test masses, will take place.The UF LIGO group gives students and postdoctoral scientists the opportunity to develop scientific skills from a diverse set of disciplines spanning lasers and optics, electronics and feedback control systems, vacuum and cryogenics, computational methods, data analysis algorithm development, and large-scale detector commissioning and operation. The University of Florida LIGO group places high value on the education of undergraduate students and each year has involved undergraduates in research. In addition, the group has a strong tradition of mentoring students and postdocs in the UF LIGO laboratory; many of these students have gone on to further education and careers in gravitational wave science. These efforts will continue. This work will positively impact the national and international scientific infrastructure through UF LIGO direct participation in research and operations at the LIGO Observatories. Finally, the proposed research has impacts that go beyond gravitational wave science. High-power optical devices developed in this project have commercial applications to the laser and optics industries.
