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 the University of Maryland College Park in their leadership roles in the operation of the observatory and in the scientific analysis of the HAWC data. The group will continue activities to optimize the sensitivity of the observatory and pursue scientific research on transient gamma-ray sources and newly discovered very high energy sources. This award will allow the group to continue and expand their outreach efforts, which include outreach to the Hispanic-American community with bi-lingual products related to HAWC. With its large instantaneous field of view and continuous operations HAWC surveys two-thirds of the sky every day. The University of Maryland group will continue their study of transient sources with HAWC as part of a multi-messenger and multi-wavelength campaign. They will also continue their work producing maps and conducting surveys to reveal new high energy gamma-ray sources. In addition, they will continue to lead the effort to exploit the novel water Cherenkov detection technique to improve the sensitivity of HAWC.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。高海拔水切伦科夫（HAWC）天文台位于墨西哥Sierra Negra的斜坡上，是一个地面设施，具有观测极高能量伽马射线的独特能力。该奖项支持马里兰州大学帕克分校的科学家在天文台的运作和HAWC数据的科学分析中发挥领导作用。该小组将继续开展活动，优化观测台的灵敏度，并对瞬变伽马射线源和新发现的甚高能量源进行科学研究。该奖项将使该集团能够继续并扩大其外联工作，其中包括与HAWC有关的双语产品向西班牙裔美国人社区进行外联。凭借其巨大的瞬时视野和连续的操作，HAWC每天可以观测三分之二的天空。 马里兰州大学小组将继续利用HAWC研究瞬态源，作为多信使和多波长活动的一部分。 他们还将继续绘制地图和进行调查，以揭示新的高能伽马射线源。 此外，他们将继续领导开发新的水切伦科夫探测技术，以提高HAWC的灵敏度。该奖项反映了NSF的法定使命，并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，被认为值得支持。
