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.

该奖项支持相对论和相对论天体物理学的研究，并介绍了NSF“宇宙上的Windows”的优先领域。引力波检测推动了大自然极端发现的深刻发现，并在先前隐藏的宇宙现象上打开了新的门。新物理学将来自重力波源的一致电磁或颗粒（例如神经元）的特征。发现意外关键的能力取决于对Ligo（激光干涉仪重力波观测站）的详细理解及其无数数据通道，从而将偶然的天体物理学与噪声的机会重合区分开来。哥伦比亚实验重力小组（GECO）旨在通过发现看似偶然的偶然性来扩大Ligo Science的覆盖范围 - 是在引力波探测器网络中的多人发现或同意非物体签名 - 同时还训练下一代科学家和工程师和工程师的下一代。 Ligo的高复杂性在我们时代提供了独特的训练场，当时科学和商业仪器的复杂性爆炸爆炸以及训练有素的STEM思维的可用性是保持节奏的。GravitationalWave提供了一个前所未有的机会，可以使用多个天体物理学使者来实现宇宙谜题。发现的根源是对仪器和创新数据分析方法之间多方面相互作用的深入了解，依靠所有可访问的数据和辅助渠道，同时还密切关注宇宙使者的全面网格。在仪器边界上，GECO将研究噪声转变及其与检测器异常的联系。使用收集的重力波触发事件，GECO将在多机天体物理学的背景下对可能的源群体以及其他源群体提供统计推断。 GECO将进行天体物理学搜索，除了强调高能量中断的GW之外，使用多个宇宙使者。该奖项反映了NSF的法定任务，并被认为是通过基金会的智力优点和更广泛的影响审查标准通过评估来评估的。
