Ultra-high-energy neutrinos are unique astrophysical messengers as they interact only weakly with intervening matter and can therefore be used to probe high energy sources and extreme conditions throughout the universe, and to test physics at energies beyond the Standard Model. This award will support a group at Ohio State University in their work to develop new technology and techniques to study high energy neutrinos through the radio emission generated as the neutrinos traverse dense ice. The group's effort focus on the Askaryan Radio Array (ARA), an experiment located at the South Pole Station in Antarctica. The group engages students at all levels in the research activities. They conduct a biannual workshop for high school women, ASPIRE. Through this award, they will add more research projects to the program and introduce research mentors for interested ASPIRE participants. The Ohio State group will focus on new strategies and techniques to process signals from current Askaryan radio neutrino experiments, with a focus on ARA. The group will study circularly polarized components of signals to complement current measurements of linear polarization and explore variations in time and directional windows to reduce background levels. They will carry out sensitive searches in existing data sets and in new ARA data for coincident detections with the IceCube observatory. They will also search for evidence of gamma-ray bursts as well as gravitational wave events in the neutrino data.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.

超高能中微子是独特的天体物理信使，因为它们只与介入物质发生微弱的相互作用，因此可以用于探测整个宇宙的高能量源和极端条件，并在超出标准模型的能量下测试物理学。 该奖项将支持俄亥俄州州立大学的一个小组，他们的工作是开发新的技术和方法，通过中微子穿越致密冰时产生的无线电发射来研究高能中微子。 该小组的工作重点是Askaryan无线电阵列（ARA），这是位于南极洲南极站的一项实验。 该小组让各级学生参与研究活动。 他们为高中女生举办了一年两次的讲习班，ASPIRE。 通过这个奖项，他们将增加更多的研究项目的计划，并介绍研究导师感兴趣的ASPIRE参与者。 俄亥俄州小组将专注于新的策略和技术，以处理来自当前Askaryan无线电中微子实验的信号，重点是ARA。 该小组将研究信号的圆偏振分量，以补充目前对线性偏振的测量，并探索时间和方向窗口的变化，以降低背景水平。 他们将在现有数据集和新的ARA数据中进行敏感搜索，以便与IceCube天文台进行同步检测。 他们还将在中微子数据中寻找伽马射线爆发和引力波事件的证据。该奖项反映了NSF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。
