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

将开展先进引力波探测器的数据分析和仪器科学研究。将开发和实施利用探测器网络对引力波爆发的相干搜索。特别注意的是中等质量的二元黑洞合并和高度偏心轨道的二元系统。将开发在线脉冲串搜索，以便能够联合进行引力波和电磁观测。将生成随机中间数据用于随机搜索，例如分析长持续时间瞬变的搜索。在仪器科学方面，将开展热自适应模式匹配、光束抖动抑制装置和改进波前传感方面的工作。展望未来，低温材料和设备的研究，包括硅的测试质量，将发生。用友LIGO集团为学生和博士后科学家提供了机会，发展科学技能，从不同的学科跨越激光和光学，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，及大型检测仪的调试和运行。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实验室指导学生和博士后的传统很强;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，拟议中的研究具有超越引力波科学的影响。本计画所开发之高功率光学元件已在雷射及光学产业上有商业应用。

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.
