RAPID: Time-Critical Enhancements for the Radio Neutrino Observatory in Greenland (RNO-G)

格陵兰射电中微子天文台（RNO-G）是一个由欧洲领导的项目，目的是在顶峰站建立一个大型地面射电阵列，首次探测到最高能量的天体物理中微子。RNO-G将是一个由35个无线电探测器组成的阵列，分布在一个1公里长的网格中，首批10个将在2021年夏季安装。该奖项支持芝加哥大学小组，该小组一直深入参与RNO-G的开发和规划，为第一个部署季节的成功提供关键的时间工具和研究。该项目将实现实时通信和数据监测，通过RNO-G实现早期的第一个科学结果和早期的多信使天体物理学研究。如果没有这些工具和研究，RNO-G将大大减少，科学成果将被推迟，美国将失去在NSF运营的一个台站进行的重要实验的宝贵参与。RNO-G团队与冰川学家和生物学家在顶峰站进行广泛的科学研究，可以详细测量地表高程，水平冰流，分析路径延迟效应和反射测量。北极研究引起了越来越多的公众兴趣，私人计划参与了阿德勒天文馆的外展项目，这些项目从私人计划在格陵兰岛的实践经验中受益匪浅。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。

The Radio Neutrino Observatory in Greenland (RNO-G) is a European-led effort to construct a large ground-based radio array at Summit Station to make the first detection of the highest energy astrophysical neutrinos. RNO-G will be an array of 35 radio detectors spread in a 1 km grid, with the first 10 to be installed during the summer of 2021. This award supports the University of Chicago group, which has been deeply involved with the development and planning for RNO-G, to provide time-critical tools and studies that are essential for the success of this first deployment season. This project will enable real-time communications and data monitoring, leading to earlier first science results and early multi-messenger astrophysics studies with RNO-G. Without these tools and studies, RNO-G will be significantly diminished, science results will be delayed, and the US will lose valuable involvement in an important experiment at a station that NSF operates.RNO-G teams with glaciologists and biologists for a broad range of science at Summit Station, enabling detailed measurements of surface elevation, horizontal ice flow, analysis of path-delay effects, and reflectometry. Arctic studies are of increasing public interest and the PI is involved with outreach programs at the Adler Planetarium, which benefit significantly from the PI’s hands-on experience in Greenland.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.
