This award supports research in relativity and relativistic astrophysics and it addresses the priority areas of NSF's "Windows on the Universe" Big Idea. Observations of high energy astrophysical neutrinos further our understanding of the most powerful cosmic ray accelerators and explosive events in the universe. Combining astrophysical neutrino observations with observations from other messengers like photons, cosmic rays, and gravitational waves allows us to view the most violent processes in the universe through multiple lenses and make new insights into the physics that drives them. Neutrino observations with IceCube have shown that the neutrino sky is complex and dynamic, revealing both an unresolved, but steady, background of neutrinos and flares of neutrinos associated with a blazar. The work performed under this award will establish the first connection between a radio neutrino telescope and other multi-messenger observatories, expanding our multi-messenger view of the universe to include the highest-energy neutrinos. In addition, this work will enable a broad range of interdisciplinary science, from glaciology to biology, and engage people from a broad range of backgrounds from around the world in multi-messenger astrophysics.The Radio Neutrino Observatory in Greenland is currently under construction at Summit Station and is optimized to search for the radio flash generated by neutrino interactions in polar ice, building on the combined successes and expertise of earlier generations of radio detectors. Its leading sensitivity, large footprint, and precision pointing will deliver unprecedented measurements of the high-energy neutrino flux. RNO-G is also the first ultra-high energy neutrino observatory with a view of the Northern sky. As such it has unique capabilities for multi-messenger observations of the highest energy neutrinos sources, including those initiated by lower-energy neutrino observations made with IceCube. The work performed under this award will provide the necessary upgrades to the RNO-G project, as it is being built, to realize its potential as a state-of-the-art instrument fully integrated into the world-wide network of multi-messenger observatories. This proposed program will improve RNO-G's sensitivity and angular resolution and enable it to respond rapidly to important targets, necessary advancements for multi-messenger campaigns. This work will lay the groundwork to provide the broader multi-messenger community high-quality event reconstructions shortly after the first high-energy neutrino candidates are identified. Under this award, the proposal team will (1) enhance neutrino pointing resolution through improved antenna designs and coincident observations in multiple stations, (2) develop real-time event processing capabilities, allowing for quicker turnaround on candidates and increased trigger rates to improve sensitivity, and (3) enable RNO-G to respond to incoming multi-messenger alerts from leading observatories, temporarily boosting sensitivity in the alert direction. The team will use these advances to conduct the first searches for multi-messenger point sources and transient sources with RNO-G.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，并解决了NSF“宇宙之窗”大理念的优先领域。对高能天体物理中微子的观测进一步加深了我们对宇宙中最强大的宇宙射线加速器和爆炸事件的理解。 将天体物理学中微子观测与光子、宇宙射线和引力波等其他信使的观测相结合，使我们能够通过多个镜头观察宇宙中最激烈的过程，并对驱动它们的物理学产生新的见解。 冰立方的中微子观测表明中微子天空是复杂和动态的，揭示了一个未解决的，但稳定的中微子背景和与耀变体相关的中微子耀斑。在该奖项下进行的工作将建立无线电中微子望远镜和其他多信使天文台之间的第一个联系，扩大我们对宇宙的多信使观点，包括最高能量的中微子。 此外，这项工作将使从冰川学到生物学的广泛的跨学科科学成为可能，并使来自世界各地的各种背景的人参与多信使天体物理学。格陵兰的射电中微子天文台目前正在Summit站建造，并进行了优化，以搜索极地冰中中微子相互作用产生的射电闪光，基于前几代无线电探测器的综合成功和专业知识。其领先的灵敏度、大尺寸和精确指向将提供前所未有的高能中微子通量测量。 RNO-G也是第一个可以看到北方天空的超高能中微子天文台。因此，它具有对最高能量中微子源进行多信使观测的独特能力，包括由IceCube进行的低能中微子观测所引发的中微子源。在该合同下完成的工作将为RNO-G项目提供必要的升级，因为它正在建设中，以实现其作为一个完全融入世界范围多信使观测站网络的最先进仪器的潜力。该计划将提高RNO-G的灵敏度和角分辨率，使其能够对重要目标做出快速反应，这是多信使战役的必要进步。 这项工作将奠定基础，提供更广泛的多信使社区高质量的事件重建后不久，第一个高能中微子候选人被确定。 根据该合同，提案团队将（1）通过改进天线设计和多个台站的同步观测来提高中微子指向分辨率，（2）开发实时事件处理能力，允许更快地周转候选人和增加触发率以提高灵敏度，以及（3）使RNO-G能够响应来自领先天文台的传入多信使警报，暂时提高了警报方向的灵敏度。该团队将利用这些进步进行多信使点源和瞬态源与RNO-G的第一次搜索。该奖项反映了NSF的法定使命，并已被认为是值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估的支持。
