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

由于新的技术，引力波和高能中微子可以在银河系附近很远的地方被探测到。它们交织在一起的信号来自一个共同的宇宙来源，可能随时到达我们这个宇宙的角落。即使从单一的难以捉摸的宇宙源中获得的洞察力也有望是深刻的。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，这些前沿技术旨在发现以前难以捉摸的宇宙信使，并了解对每个人都有用的统计概念，这些概念在日常生活中经常被教育系统所忽略。PI的小组将培训STEM学科的学生，并通过公开演讲与普通观众接触。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，它们的声音不足以宣布探测到，并且它们与复杂的过多的探测器噪声瞬态交织在一起。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，将通过提供受限定位来促进联合引力波-中微子候选者的电磁后续观测，并通过发现或建立它们的数量限制来推进天体物理学的发展。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知识价值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.
