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 High Altitude Water Cherenkov (HAWC) observatory, located on the slopes of the Sierra Negra in Mexico, is a ground-based facility designed with unique capabilities to observe very high-energy gamma-rays. This award supports scientists at Michigan Technological University doing research with HAWC. In addition to hardware and service activities to support HAWC operations, the group will analyze HAWC data to study the origin of cosmic rays. The group will engage in education and outreach activities, including the University's Summer Youth Program for high-school students. High-energy gamma-rays are produced when cosmic rays interact with their local environment, interstellar matter and radiation fields. As neutral particles these gamma-rays can be traced back to their origin and used to provide critical information on the origin of cosmic rays. The Michigan group will perform detailed studies of point, extended, and diffuse Galactic gamma-ray source emission, including studies of the morphology and spectral energy distributions to study the origin of cosmic rays. The results using data from the HAWC Observatory will complement and can be combined with measurements by other space and ground-based gamma-ray observatories.

伽马射线是电磁辐射的最高能量形式。 天体物理伽马射线的观测可以作为整个宇宙最极端环境中物理条件和过程的探测器，并可用于测试基础物理。 高海拔水切伦科夫（HAWC）天文台位于墨西哥内格拉山脉的山坡上，是一个地面设施，具有独特的观测极高能伽马射线的能力。 该奖项支持密歇根理工大学的科学家与 HAWC 进行研究。 除了支持 HAWC 运行的硬件和服务活动外，该小组还将分析 HAWC 数据以研究宇宙射线的起源。 该小组将从事教育和外展活动，包括大学针对高中生的暑期青年计划。当宇宙射线与其局部环境、星际物质和辐射场相互作用时，就会产生高能伽马射线。 作为中性粒子，这些伽马射线可以追溯到它们的起源，并用于提供有关宇宙射线起源的关键信息。 密歇根小组将对点、扩展和扩散银河伽马射线源发射进行详细研究，包括形态和光谱能量分布的研究，以研究宇宙射线的起源。 使用 HAWC 天文台数据得出的结果将补充并可与其他空间和地面伽马射线天文台的测量结果相结合。
