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. With its large instantaneous field of view and continuous operations HAWC surveys two-thirds of the sky every day. HAWC observations have provided new views of the high energy sky and led to the discovery of new sources. This award to the University of Maryland College Park supports the continued operation of HAWC. This award will also support HAWC's public outreach programs that include outreach to the Hispanic-American community with bi-lingual products related to HAWC. HAWC will continue to perform deep surveys of the gamma-ray sky and will observe a large sample of gamma-ray sources with measurements of flux, spectra and variability. HAWC's wide field and high sensitivity enable studies of extended sources and diffuse emission from the Galactic plane. HAWC plays an important role in multi-wavelength and multi-messenger astrophysics campaigns. The University of Maryland plays a critical role in HAWC operations. The PI serves as U.S. Spokesperson for HAWC and the Co-PI serves as HAWC Data Manager. With this award they will continue to operate and maintain the HAWC observatory, maintain the US data archive, and provide public data access to sky maps and real-time transient alerts.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。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。 凭借其巨大的瞬时视场和连续运行，HAWC 每天勘测三分之二的天空。 HAWC 观测提供了高能天空的新视角，并导致了新来源的发现。 该奖项授予马里兰大学学院公园分校，支持 HAWC 的持续运营。 该奖项还将支持 HAWC 的公共推广计划，其中包括通过与 HAWC 相关的双语产品向西班牙裔美国人社区进行推广。 HAWC 将继续对伽马射线天空进行深入调查，并将观测大量伽马射线源样本，测量通量、光谱和变异性。 HAWC 的宽视场和高灵敏度使得能够研究银河平面的扩展源和漫射发射。 HAWC 在多波长和多信使天体物理活动中发挥着重要作用。 马里兰大学在 HAWC 运营中发挥着关键作用。 PI 担任 HAWC 美国发言人，Co-PI 担任 HAWC 数据经理。 获得该奖项后，他们将继续运营和维护 HAWC 天文台，维护美国数据档案，并提供天空图和实时瞬态警报的公共数据访问。该奖项反映了 NSF 的法定使命，并通过评估认为值得支持利用基金会的智力优势和更广泛的影响审查标准。
