Gamma rays are the highest energy form of electromagnetic radiation. Observations of astrophysical gamma rays serve as probes of physical conditions and processes in the most extreme environments throughout the Universe and can be used to test fundamental physics. The Very Energetic Radiation Imaging Telescope Array System (VERITAS), located in southern Arizona, is a ground-based observatory designed to study high-energy gamma rays. VERITAS has unique capabilities, providing high sensitivity pointed observations of both galactic and extragalactic sources. This award supports scientists at the University of Alabama to carry out research with VERITAS. The group will use VERITAS observations to search for gamma-ray counterparts of high-energy neutrinos detected by the IceCube observatory and of gravitational wave events detected by the LIGO observatory. The group is involved in training and development activities for undergraduates working in multi-messenger astrophysics with particular emphasis on members of historically under-represented groups in STEM fields.The University of Alabama group will focus on the following multi-messenger astrophysics studies: a search for very high energy gamma-ray emission in coincidence with archival and newly-detected high-energy astrophysical neutrino event candidates from the IceCube observatory; a detailed study of TXS 0506+056, the first VHE gamma ray source detected in coincidence with a high energy astrophysical neutrino; a comprehensive study of gamma-ray observations of bright blazars and other types of extragalactic sources that are potential neutrino emitters to probe their emission mechanisms; and the search for very high energy gamma-ray counterparts for gravitational wave events produced by LIGO. The group at the University of Alabama will continue efforts related to the next-generation Cherenkov Telescope Array by participating in the development and commissioning of a prototype air Cherenkov telescope at the VERITAS site in Arizona. This work directly addresses the goals of NSF's "Windows on the Universe: The Era of Multi-Messenger Astrophysics" Big Idea.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.

伽马射线是电磁辐射的最高能量形式。对天体物理学伽马射线的观测可以作为整个宇宙中最极端环境中的物理条件和过程的探测器，并可用于测试基础物理学。 高能辐射成像望远镜阵列系统（VERITAS）位于亚利桑那州南部，是一个地面观测站，旨在研究高能伽马射线。VERITAS具有独特的能力，可提供对银河系和河外来源的高灵敏度定点观测。该奖项支持亚拉巴马大学的科学家与VERITAS一起开展研究。 该小组将使用VERITAS观测来搜索IceCube天文台探测到的高能中微子和LIGO天文台探测到的引力波事件的伽马射线对应物。 该小组参与了多信使天体物理学本科生的培训和发展活动，特别强调了STEM领域历史上代表性不足的群体的成员。亚拉巴马大学小组将专注于以下多信使天体物理学研究：寻找非常高能量的伽马射线发射与档案和新探测到的高-来自冰立方天文台的能量天体物理中微子事件候选者;对TXS 0506+056的详细研究，这是第一个与高能天体物理中微子重合的VHE伽马射线源;对明亮的耀变体和其他类型的河外源进行伽马射线观测的综合研究，这些源是潜在的中微子发射源，以探测其发射机制;以及寻找由LIGO产生的引力波事件的非常高能量的伽马射线对应物。 亚拉巴马大学的研究小组将继续开展与下一代切伦科夫望远镜阵列有关的工作，参与亚利桑那州VERITAS站点的原型空中切伦科夫望远镜的开发和试运行。 这项工作直接解决了NSF的“宇宙之窗：多信使天体物理学时代”的目标。该奖项反映了NSF的法定使命，并已被认为值得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来支持。
