Observations of astrophysical gamma-rays, the highest energy form of electromagnetic radiation, provide the ability to study the conditions and processes in the most extreme astrophysical environments in the Universe. The High Altitude Water Cherenkov (HAWC) observatory, located in the Sierra Negra in Mexico, provides a unique view on gamma-ray emission from hundreds of GeV to beyond 100 TeV. This award supports scientists at Michigan Technological University performing research with HAWC. Analyses of the HAWC data will be used to improve the understanding of cosmic ray acceleration and transport by tracing the interactions with matter and radiation fields in the Universe that produce gamma-rays. The team will participate in education and outreach activities, including developing a Research Experience for Teachers program that will create lesson plans for gamma-ray and multi-messenger astronomy for use in high school and community college classrooms and summer youth programs. The HAWC observatory provides a unique view of the gamma-ray sky, with a nearly 100% duty cycle and an instantaneous field-of-view of about 2 steradians. With realized improvements in the sensitivity, and the image and energy resolution of the observatory, HAWC has measured the most extensive TeV-scale gamma-ray dataset of the northern hemisphere sky. Employing state-of-the-art statistical methods and combining data from the observatory with multi-messenger data has the potential to significantly improve our understanding of extreme sources of cosmic ray origin, acceleration, and transport. At the same time, enhancing the accessibility of HAWC data to the multi-messenger community maximizes the science return, in particular in studies of a number of source classes including star forming regions, supernova remnants, pulsar wind nebulae, 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.

天体物理伽马射线的观察是电磁辐射的最高能量形式，它提供了研究宇宙中最极端的天体物理环境中的条件和过程的能力。 位于墨西哥塞拉内格拉（Sierra Negra）的高空水Cherenkov（HAWC）天文台提供了关于伽马射线发射的独特视图，从数百GEV到100 TEV以上。 该奖项支持密歇根技术大学的科学家与HAWC进行研究。 HAWC数据的分析将用于通过追踪与产生伽玛射线的宇宙的物质和辐射场相互作用，以提高对宇宙射线加速度和运输的理解。 该团队将参加教育和外展活动，包括为教师计划开发研究经验，该计划将为伽玛射线和多门交易者天文学创建课程计划，用于在高中和社区大学教室和夏季青年计划中使用。 HAWC天文台提供了伽马射线天空的独特视图，其占空比近100％，并且是大约2个Steradians的瞬时视野。随着敏感性的改善以及天文台的图像和能量解析，HAWC测量了北半球天空中最广泛的TEV尺度伽马射线数据集。 采用最先进的统计方法并将观测值的数据与多通间的数据结合在一起，有可能显着提高我们对宇宙射线起源，加速和运输的极端来源的理解。 同时，增强HAWC数据对多通信社区的可访问性最大化科学回报，尤其是在许多来源类别的研究中，包括恒星形成区域，超新星残留物，脉冲星风星和二进制系统。 该项目促进了NSF Windows在宇宙大想法上的目标。该奖项反映了NSF的法定任务，并且使用基金会的知识分子优点和更广泛的影响审查标准，被认为值得通过评估来获得支持。
