PI: Dimitrios Psaltis (University of Arizona)co-PIs: Sheperd Doeleman (Harvard University)Charles Gammie (University of Illinois)Daniel Marrone (University of Arizona)Feryal Ozel (University of Arizona)Non-Technical Explanation:The Event Horizon Telescope (EHT) is an Earth-sized array of telescopes that aims to obtain the first ever images of astrophysical black holes and test Einstein's theory of general relativity in extreme conditions. The project is inherently international and multidisciplinary, involving telescopes and institutions on five continents and requiring expertise in areas ranging from detector development to high-performance computing and theoretical physics. The PIRE project team will integrate researchers in the U.S., Germany, Mexico, and Taiwan and usher astronomical projects, such as the EHT, into the era of big and distributed data science. The PIRE award will fund activities in detector development, in mounting coordinated observations, in fast data transfer between partner institutions, and in cloud computing that will realize the scientific potential of the observations. The project activities, summer schools, and webinars will enable the education of students and early career researchers with internationally collaborative, hands-on experience in state-of-the-art instrumentation technology, high-performance computing, and big data science. The PIRE will also provide critical experience to young researchers in navigating large, complex international collaborations. The tools developed under this PIRE award will be openly available to the broader community to directly benefit all other projects that rely on distributed resources and expertise. The compelling combination of the first images of black holes, the visually stunning results of computer simulations, and the use of virtual reality tools will engage the public in the fascinating astrophysics of black holes and inspire aspiring and future STEM students.Technical Description:The EHT generates data and computational products distributed on a global scale at a rate that pushes the limits of the current infrastructure for sharing and analysis. The proposed PIRE award will support the goal of studying black holes with the EHT at unprecedented angular resolution by funding activities to develop: (i) advanced technologies to increase the efficiency of observations; (ii) algorithms for optimizing the scheduling and triggering of world-wide campaigns; (iii) infrastructure to facilitate fast transfer and sharing large volumes of data among participating institutions; and (iv) cloud computing frameworks to realize the scientific potential of the observations by supporting advanced modeling and analysis efforts. The unique opportunities that the international partners bring to the PIRE project include developing the infrastructure that accelerates the worldwide sharing of data, tools, and resources in order to fundamentally transform the way international and multifaceted collaborations, such as the EHT, are utilized. The proposed PIRE award will engage undergraduates, graduate students, and postdoctoral associates in a three-continent project with annual summer schools alternating between the four member countries. This will be augmented by monthly webinars, hackathons, and regular exchange visits among partner institutions. The educational outcome of this collaboration will be monitored and continuously improved by using advanced assessment tools.

PI：Dimitrios Psaltis（亚利桑那大学）Co-Pis：Sheperd Doeleman（哈佛大学）Charles Gammie（伊利诺伊大学）Daniel Marrone（亚利桑那大学）Feryal Ozel（亚利桑那大学）非技术性解释：活动视野（活动视野远程） EHT）是一系列地球大小的望远镜，旨在获取有史以来第一个天体物理黑洞的图像，并在极端条件下测试爱因斯坦的一般相对性理论。该项目本质上是国际和多学科的，涉及五大洲的望远镜和机构，并且需要在探测器发展到高性能计算和理论物理学等领域的专业知识。 PIRE项目团队将在美国，德国，墨西哥，台湾和Unher天文项目（例如EHT）中将研究人员整合到大型和分布式数据科学时代。 PIRE奖将资助探测器开发，安装协调观察，合作伙伴机构之间的快速数据传输以及将实现观察的科学潜力的活动。项目活动，暑期学校和网络研讨会将使学生和早期职业研究人员在最先进的仪器技术，高性能计算和大数据科学方面具有国际协作，动手实践经验的教育。海盗还将为年轻研究人员提供重要的经验，以导航大型，复杂的国际合作。根据该PIRE奖开发的工具将公开向更广泛的社区公开，以直接使所有依赖分布式资源和专业知识的项目受益。黑洞的第一批图像，计算机模拟的视觉令人惊叹的结果以及使用虚拟现实工具的引人入胜的组合将吸引公众参与令人着迷的黑洞的迷人天体物理学，并激发了有抱负和未来的STEM学生。技术描述：EHT生成以全球范围分布的数据和计算产品，以推动当前基础架构进行共享和分析的限制。拟议的PIRE奖将支持通过为开发的资助活动以前所未有的角度分辨率研究黑洞的目标：（i）提高观察效率的先进技术； （ii）优化全球广告系列计划和触发的算法； （iii）基础设施促进参与机构之间的快速转移并共享大量数据； （iv）云计算框架通过支持先进的建模和分析工作来实现观察结果的科学潜力。国际合作伙伴带给PIRE项目的独特机会包括开发基础架构，这些基础架构加速了全球数据，工具和资源的共享，以从根本上改变国际和多方面的合作（例如EHT）的方式。拟议的PIRE奖将使本科生，研究生和博士后同事参与一个三大项目，每年暑期学校在四个成员国之间交替。每月的网络研讨会，黑客马拉松和合作伙伴机构的定期交流访问将增加这一点。通过使用高级评估工具，将监控和不断改进这项合作的教育结果。
