High-energy gamma-radiation represents one of the key messengers of the extreme universe, in particular providing insight into the cosmic ray accelerators that produce the highest energy particles observed. The award supports the activities of researchers at the University of Utah for on-going participation in observations and analysis of data from the High Altitude Water Cherenkov (HAWC) and VERITAS observatories, and the future Cherenkov Telescope Array (CTA) observatory. Students and postdoctoral researchers supported by this grant will explore the origin of the high-energy gamma-radiation emitted by black holes, neutron stars, and supernova remnants. In addition, the researchers will develop ultra-high-resolution visible-light observations to accurately measure the diameters and create images of nearby stars using the VERITAS Stellar Intensity Interferometry Observatory. The award supports an extensive training program for undergraduate students who do not otherwise have access to extensive research facilities, and activities that explore the connections between astronomical dark skies, urban planning, biodiversity and microclimate, workforce diversity, and economic opportunity through the University’s Consortium for Dark Sky Studies.Recent advances in multi-wavelength analyses developed by the researchers provide a framework to explore possible astrophysical origins of galactic cosmic rays and the observed local positron flux. This includes studies of archival and new VERITAS observations of promising TeV halo regions identified from current all-sky catalogs published by the Fermi satellite Observatory, and the HAWC northern-sky surveys. Next steps will realize improved gamma-ray observations with the newly-developed wide-field of view Schwartzchild-Couder Telescope and result in integrating these elements, the Multi-Messenger Maximum Likelihood analysis framework (3ML), and Matched Run Method analysis tools to the GammaPy analysis framework, for use by the future CTA observatory. Completing the program is a survey of stellar diameters measured in the U/V optical bands via intensity interferometry observations with the VERITAS telescopes that will permit development of a suite of analysis tools for imaging of O/B/A stars, Cepheid variables, and binary systems. This project advances the goals of the NSF Windows on the Universe 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.

高能量伽玛辐射是极端宇宙的关键使者之一，特别是对产生观察到的最高能量颗粒的宇宙射线加速器的见解。该奖项支持犹他大学的研究人员的活动，以持续参与观察和分析来自高空水Cherenkov（HAWC）和Veritas观察的数据，以及未来的Cherenkov望远镜阵列（CTA）观察者。这笔赠款支持的学生和博士后研究人员将探索黑洞，中子星和超新星残留物发出的高能伽玛辐射的起源。此外，研究人员将使用Veritas Stellar强度干涉测定法观察到准确测量直径并创建附近恒星的图像，从而开发超高分辨率的可见光观测值。该奖项为本科生提供了广泛的培训计划，这些培训课程否则就无法获得广泛的研究设施，以及探索天文学的黑暗天空，城市规划，生物多样性和微气候，劳动力多样性，通过大学的经济机会，通过大学的黑暗天空研究提供的众多研究群体的群体，以探索众多属性的赛场，以探索众多的进步。宇宙射线和观察到的局部正电子通量。这包括对从费米卫星天文台发布的当前全套目录和HAWC North-Sky Surveys确定的对档案和新的Veritas观察结果。接下来的步骤将通过新开发的视图Schwartzchild-couder望远镜来实现改进的伽马射线观察结果，并导致整合这些元素，Multi-Messenger最大似然分析框架（3ML），并匹配的运行方法分析工具与未来CTA观察的胶水疗法分析工具与伽马疗法分析框架相匹配。完成该程序的是对通过Veritas望远镜进行强度干扰观察在U/V光节中测得的恒星直径的调查，该观察将允许开发一套分析工具，用于成像O/B/A星星，头孢虫变量和二进制系统。该项目促进了NSF Windows在宇宙大概念上的目标。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的审查标准来诚实地通过评估来诚实地支持。
