The Very Energetic Radiation Imaging Telescope Array System (VERITAS), located at the F. L. Whipple Observatory basecamp of Mt. Hopkins, AZ, is in a full science-driven mode. The array consists of four Imaging Atmospheric Cherenkov Telescopes (IACTs), allowing observations of very-high-energy (VHE) gamma rays above an energy threshold of 50 GeV to detect exotic sources of VHE gamma rays throughout the galaxy and extra-galactic space, probing the extreme physics of sources such as the jets of Active Galactic Nuclei (AGN), supernova remnants and microquasars. VERITAS is well-positioned to complement the Fermi Gamma-ray Space Telescope launched by NASA in June 2008 where the two observatories together provide overlapping spectral coverage from the tens of MeV to tens of TeV range.This award will provide this University of Minnesota (UMN) group with base support of their VERITAS science and collaboration service efforts over the next three years. The group will continue development of improved analysis techniques using advanced multivariate algorithms developed by the High Energy Physics community. Their scientific analysis efforts will be in studies of extragalactic sources including AGN, starburst galaxies, and galaxy clusters with a focus on locating the source of gamma-ray emission in blazars and understanding the origin of cosmic rays. The group will continue to lead the VERITAS multi-wavelength coordination efforts and, in particular, will bring the new important resource of optical polarimetry to the multi-wavelength study of blazar emission zones. The team will also contribute multiwavelength correlation studies complementing the TeV data obtained with VERITAS. Broader Impact: The outreach effort has two components. The first is to work with the established Research Experiences for Undergraduates program at UMN to actively mentor undergraduates on a VERITAS-related project each summer. The second component is to select at least one undergraduate to participate in the Adler Planetarium's VERITAS EPO program which recruits students from VERITAS collaborating institutions to work with scientists in the Adler's Space Visualization Laboratory to develop gamma-ray computer interactives.

位于亚利桑那州霍普金斯山的F. L. Whipple天文台基地，非常有力的辐射成像望远镜阵列系统（VERITAS）处于完整的科学驱动模式。 The array consists of four Imaging Atmospheric Cherenkov Telescopes (IACTs), allowing observations of very-high-energy (VHE) gamma rays above an energy threshold of 50 GeV to detect exotic sources of VHE gamma rays throughout the galaxy and extra-galactic space, probing the extreme physics of sources such as the jets of Active Galactic Nuclei (AGN),超新星残留物和微夸拉。 Veritas的位置很好，可以补充NASA于2008年6月推出的Fermi Gamma-ray太空望远镜，在2008年6月，这两个观测站共同提供了从MEV数十亿到TEV范围的重叠频谱覆盖范围。这项奖项将提供这项明尼苏达大学（UMN）（UMN）（UMN）的小组，并提供了与他们的Veritas Science和Seconcloration Science和Seconallocation Service Service Service Service of Seconal Science和Seconal Service Service Service of Seconal Science和Section Service Service Service of Seconal Science。该小组将使用高能量物理社区开发的高级多元算法继续开发改进的分析技术。他们的科学分析工作将是研究包括AGN，Starburst星系和星系簇在内的研究，重点是在Blazars中找到伽马射线排放的来源，并了解宇宙射线的起源。该小组将继续领导Veritas多波长的协调工作，尤其是将光学偏振法的新重要资源带入大黄花发射区的多波长研究。该团队还将贡献多波长相关研究，以补充用Veritas获得的TEV数据。更广泛的影响：外展工作有两个组成部分。首先是与UMN的本科生计划的既定研究经历合作，以在每年夏天在一个与Veritas相关的项目上积极指导本科生。第二部分是选择至少一个本科生参加Adler Planetarium的Veritas EPO计划，该计划招募了Veritas合作机构的学生与Adler Space可视化实验室中的科学家合作，以开发Gamma-Ray计算机交互。
