As a result of novel enabling technologies, gravitational waves and high-energy neutrinos are detectable far beyond our galactic neighborhood. Their intertwined signature from a common cosmic source may reach our corner of the Universe at any instant. The insight gained even from a single joint elusive cosmic source is expected to be profound. Additionally, multimessenger science -- through its complexity -- provides a remarkable synergy with frontier technologies built to uncover previously elusive cosmic messengers and to learn about statistical concepts that are useful for everyone in everyday life but often elude the education system. The PI's group will train students in STEM disciplines, as well as reach out to general audiences through public presentations.For every discovery of a loud gravitational-wave signal, there are numerous weak fingerprints called subthreshold candidates, not sufficiently loud to claim a detection, and they are intertwined with a complex plethora of detector noise transients. The Columbia Experimental Gravity Group will conduct in-depth analyses using these subthreshold candidates in the multimessenger context, will facilitate the electromagnetic follow-up observations of joint gravitational-wave – neutrino candidates by providing confined localization, and advance astrophysics in general by uncovering or establishing a limit on their population.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.

由于新的使能技术，引力波和高能中微子可以在远远超出我们银河系的地方被探测到。它们来自一个共同的宇宙源的相互交织的签名可能在任何时刻到达我们宇宙的角落。即使从一个单一的联合难以捉摸的宇宙来源获得的洞察力预计是深刻的。此外，多信使科学-通过其复杂性-提供了与前沿技术的显着协同作用，这些前沿技术旨在发现以前难以捉摸的宇宙信使，并了解对日常生活中的每个人都有用但往往逃避教育系统的统计概念。PI的团队将对学生进行STEM学科的培训，并通过公开演讲接触普通观众。对于每一个响亮的引力波信号的发现，都有许多被称为亚阈值候选者的微弱指纹，这些指纹不够响亮，无法声称检测到，并且它们与复杂的过多检测器噪声瞬变交织在一起。 哥伦比亚实验重力小组将在多信使背景下使用这些亚阈值候选者进行深入分析，将通过提供有限的定位来促进联合引力波中微子候选者的电磁后续观测，并通过发现或建立对它们的人口限制来推进天体物理学。该奖项反映了NSF的法定使命，并通过评估被认为值得支持使用基金会的知识价值和更广泛的影响审查标准。
