项目摘要

The LIGO gravitational wave detectors are currently undergoing a major upgrade, with the goal of improving the sensitivity by an order of magnitude. But it takes more than lasers, mirrors and photodiodes to detect gravitational waves. Another key component is the signal processing used to tease the faint gravitational wave signals out of the instrument noise. The research supported by this award seeks to develop tools that will enhance our ability to detect and characterize transient gravitational wave signals. The initial searches for gravitational waves have taught us that non-Gaussian features in the data, such as noise transients or ``glitches'', impair our ability to detect weak signals. Our goal is to develop powerful new techniques that can help separate gravitational wave signals from instrument artifacts. The detection of gravitational waves will allow a host of science questions to be addressed. Foremost among these will be whether the signals detected conform to the predictions of Einstein's theory of general relativity. This award will support the development of robust techniques for identifying departures from general relativity using LIGO/Virgo data.The LIGO project presents young researchers and students with a wonderful opportunity to participate in the birth of a new observation science that is poised to make discoveries that will revolutionize astronomy and deliver unique insights into some of the Universe's most exotic phenomena. The research program supported by this award offers tremendous opportunities for graduate and undergraduate students: the blend of creative activities associated with the development of sophisticated and innovative data analysis techniques, combined with hands on exposure to running existing search pipelines and working with production level computer code will provide excellent training for the next generation of gravitational wave astronomers. These skills are transferable and highly sought after in other fields: recent graduates from the Montana State gravitational wave astronomy group have found employment as national security intelligence analysts and in the medical research field of bioinfomatics.
LIGO引力波探测器目前正在进行重大升级,目标是将灵敏度提高一个数量级。但是探测引力波需要的不仅仅是激光器、镜子和光电二极管。另一个关键组成部分是信号处理,用于从仪器噪声中提取微弱的引力波信号。该奖项支持的研究旨在开发工具,提高我们检测和表征瞬态引力波信号的能力。对引力波的初步研究告诉我们,数据中的非高斯特征,如噪声瞬变或“毛刺”,会削弱我们检测微弱信号的能力。我们的目标是开发强大的新技术,可以帮助分离引力波信号从仪器文物。引力波的探测将使许多科学问题得到解决。其中最重要的将是检测到的信号是否符合爱因斯坦广义相对论的预测。该奖项将支持使用LIGO/Virgo数据识别广义相对论偏差的强大技术的开发。LIGO项目为年轻研究人员和学生提供了一个绝佳的机会,参与新观测科学的诞生,该科学即将做出革命性的发现天文学并对宇宙中一些最奇异的现象提供独特的见解。该奖项支持的研究计划为研究生和本科生提供了巨大的机会:与复杂和创新的数据分析技术的发展相关的创造性活动的融合,结合对现有搜索管道的实际操作以及与生产级计算机代码的合作,将为下一代引力波天文学家提供出色的培训。这些技能是可转移的,并在其他领域备受追捧:最近从蒙大拿州引力波天文学组的毕业生已经找到了国家安全情报分析师和生物信息学的医学研究领域的就业机会。
