Accreting super-massive black holes are some of the most extreme physical environments in the Universe. The relativistic outflows and jets from these systems are candidate sources of energetic cosmic rays, gamma rays and extragalactic neutrinos. These systems impact the evolution of the galaxies and clusters, from recycling of gas in cosmic fountains to heating the inter-cluster medium. This award supports scientists at the University of Maryland Baltimore County (UMBC) performing research with the Very Energetic Radiation Imaging Telescope Array System (VERITAS) at the Fred Lawrence Whipple Observatory in Arizona, USA. Specifically, the awarded program will provide improved understanding of the outflows from black holes and their impact on their hosts and environments via coordinated multiwavelength observations with VERITAS. The program will support unique training and mentoring of graduate and undergraduate student researchers in combining astrophysical data and theoretical models. In addition, with the UMBC Society of Physics students the program will develop portable detectors for public observatory nights and outreach events at local schools. VERITAS provides a targeted field of view with leading sensitivity in the measurement of gamma-rays from ~50 GeV to 500 TeV. No known astronomical sources emit solely in the very high-energy (VHE) gamma-ray band, however, and a full understanding of the physical conditions to constrain theoretical models of the source requires sampling of the full spectrum of output. Pairing VERITAS observations with the Swift X-ray observatory and ground-based optical and radio monitoring programs provides simultaneous multi-wavelength coverage and high-resolution imaging. A multi-wavelength central data ‘hub’ provides automatically updated information on target VHE astrophysical objects as well as their archival and planned observations for the approximate dozen observatories used in coordination with VERITAS. This information will prove crucial to testing long-considered models of the origin and evolution of VHE emission in jets, including their potential role as sources of energetic cosmic rays and high-energy neutrinos. 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.

吸收超质量黑洞是宇宙中最极端的物理环境。来自这些系统的相对论插座和喷气机是能量宇宙射线，伽马射线和阿加拉术神经元的候选来源。这些系统会影响星系和簇的演变，从宇宙喷泉的气体回收到加热集群间培养基。该奖项支持马里兰州巴尔的摩县（UMBC）的科学家，通过在美国亚利桑那州的Fred Lawrence Whipple天文台进行了非常充满活力的辐射成像望远镜阵列系统（VERITAS）进行研究。具体而言，授予的计划将通过与Veritas协调的多波长观测值来提高对黑洞及其对宿主和环境的影响的了解。该计划将支持研究生和本科生研究人员在合并天体物理数据和理论模型中的独特培训和心理化。此外，在UMBC物理学生的学生中，该计划将开发可移植的探测器，以在当地学校开发公众观察之夜和外展活动。 Veritas在测量伽马射线从〜50 GEV到500 TEV的测量中提供了一个具有领先灵敏度的目标视野。然而，没有已知的天文来源仅在非常高的（VHE）伽马射线带中发射，并且对限制源的理论模型的物理条件的完全理解需要对全部产出频谱进行采样。将Veritas观察与迅速的X射线观测以及地面的光学和无线电监控程序配对提供了同时的多波长覆盖范围和高分辨率成像。多波长中央数据“集线器”提供了有关目标VHE天体物理对象的自动更新信息，以及它们的档案和计划观察，以与Veritas协调时使用的大约十二个观测值。该信息将证明对测试JET中VHE发射的起源和演变的长期考虑模型至关重要，包括它们作为能量宇宙射线和高能神经元的潜在作用。该项目推动了NSF Windows在宇宙大想法上的目标。该奖项反映了NSF的法定任务，并通过使用基金会的知识分子优点和更广泛的影响评估标准来评估值得支持。
