WoU-MMA: Empowering Multimessenger Science via Improving LIGO Data

该奖项支持相对论和相对论天体物理学的研究，并阐述了美国国家科学基金会“宇宙之窗”宏伟构想的优先领域。引力波探测推动了对自然极端的深刻发现，为以前隐藏的宇宙现象打开了新的大门。引力波源的电磁或粒子(如中微子)信号的重合将产生新的物理学。发现意外的能力取决于对LIGO(激光干涉仪引力波天文台)及其无数数据通道的详细了解，这些数据通道将偶然的天体物理与噪声的偶合区分开来。哥伦比亚实验引力小组(GECO)的目标是通过发现看似偶然的事情来扩大LIGO科学的覆盖范围--无论是在引力波探测器网络中发现或同时发现非地球特征--同时也培训下一代科学家和工程师。LIGO的高度复杂性在我们这个时代提供了一个独特的训练场地，在这个时代，科学和商业仪器的复杂性爆炸式增长，需要训练有素的STEM头脑来跟上步伐。引力波提供了一个前所未有的机会，通过使用多个天体物理信使的新数据来揭示宇宙之谜。发现的根本是深入了解仪器和创新的数据分析方法之间的多方面相互作用，依赖于所有可访问的数据和辅助渠道，同时还关注宇宙信使的全面网络。在仪器前沿，GECO将研究噪声瞬变及其与探测器异常的联系。利用收集到的引力波触发事件，GECO将在多传播者天体物理的背景下，对可能的源群体等提供统计推断。GECO将执行天体物理搜索，除了GWS外，还将使用多个宇宙信使，重点是高能中微子。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

This award supports research in relativity and relativistic astrophysics and it addresses the priority areas of NSF's "Windows on the Universe" Big Idea. Gravitational wave detections drive profound discoveries at nature’s extremes, opening new doors on previously hidden cosmic phenomena. New physics will arise from coincident electromagnetic or particle (such as neutrino) signatures of gravitational wave sources. The ability to discover the unexpected critically depends on a detailed understanding of LIGO (Laser Interferometer Gravitational-wave Observatory) and its myriads of data channels distinguishing the serendipitous astrophysics from the chance coincidence of noise. The Columbia Experimental Gravity group (GECo) aims to expand the reach of LIGO science by uncovering the seemingly serendipitous - be that a multimessenger discovery or concurrence of non-terrestrial signature in a network of gravitational-wave detectors – while also training the next generation of scientists and engineers. LIGO's high complexity provides a unique training ground in our era when the complexity of scientific and commercial instruments explodes and the availability of highly trained STEM minds is needed to keep pace.Gravitational waves provide an unprecedented opportunity born of new data to expose cosmic puzzles using multiple astrophysical messengers. At the root of discovery is an in-depth understanding of the multifaceted interplay between the instruments and innovative data analysis approaches relying on all accessible data and auxiliary channels, while also keeping an eye on the comprehensive mesh of cosmic messengers. On the instrumental frontier, GECo will study noise transients and their connection to detector anomalies. Using collected gravitational wave trigger events, GECo will provide statistical inference on possible source populations, among others, in the context of multimessenger astrophysics. GECo will carry out astrophysics searches, using multiple cosmic messengers besides GWs with emphasis on high energy-neutrinos.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
