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.

由于采用了新颖的技术，引力波和高能中微子可以在远离我们银河系的地方被探测到，它们来自共同宇宙源的相互交织的信号可能随时到达我们宇宙的角落，甚至可以从单个关节中获得洞察力。此外，多信使科学通过其复杂性，与前沿技术提供了显着的协同作用，旨在揭示以前难以捉摸的宇宙信使并了解统计概念。这些对日常生活中的每个人都有用，但往往无法被教育系统所接受。PI 的团队将对学生进行 STEM 学科培训，并通过公开演讲接触到普通观众。对于每一个响亮的引力波信号的发现，都会有一些发现。大量被称为亚阈值候选的微弱指纹，声音不足以声称检测到，并且它们与大量复杂的探测器噪声瞬变交织在一起，哥伦比亚实验重力组将利用这些指纹进行深入分析。多信使背景下的亚阈值候选者，将通过提供有限的定位促进联合引力波-中微子候选者的电磁后续观测，并通过发现或建立对其数量的限制来总体上推进天体物理学。该奖项反映了美国国家科学基金会的法定使命和通过使用基金会的智力优点和更广泛的影响审查标准进行评估，该项目被认为值得支持。
