WoU-MMA: Deep Multimessenger Search for Joint Sources of Gravitational-Waves and High-Energy Neutrinos

由于新的使能技术，引力波和高能中微子在我们银河系附近的地方都能探测到。它们相互交织的信号来自一个共同的宇宙来源，随时可能到达我们宇宙的一角。即使是从一个难以捉摸的单一宇宙来源获得的洞察力，预计也将是深远的。此外，多信使科学--通过其复杂性--与前沿技术提供了显著的协同作用，这些前沿技术旨在揭示以前难以捉摸的宇宙信使，并了解统计概念，这些概念在日常生活中对每个人都有用，但往往躲避教育系统。PI的团队将对学生进行STEM学科培训，并通过公开演讲接触普通观众。每次发现巨大的引力波信号，都会有许多称为亚阈值候选的微弱指纹，这些指纹的声音不足以声称检测到了，它们与大量复杂的探测器噪声瞬变交织在一起。哥伦比亚实验引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，将通过提供受限定位来促进引力波-中微子联合候选者的电磁后续观测，并通过发现或建立对其人口的限制来促进天体物理学的总体发展。该奖项反映了美国国家科学基金会的法定使命，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。

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.
