PROPOSAL NUMBER: 0758085INSTITUTION: California Polytechnic State University FoundationNSF PROGRAM: PHY - PARTICLE ASTROPHYSICSPRINCIPAL INVESTIGATOR: Christiansen, Jodi L.TITLE: RUI: Analysis of TeV Gamma-rays and Pulsars Observed by VERITAS ABSTRACTThis RUI grant will bring astrophysics experiences to California Polytechnic State University, San Luis Obispo. VERITAS, the Very Energetic Radiation Imaging Telescope Array System, located in Southern Arizona at the Whipple Observatory Base camp, is an array of imaging atmospheric Cherenkov telescopes designed to detect very-high-energy (VHE) gamma rays (100 GeV ? 50 TeV) that shower in the earth?s atmosphere. Active galaxies (AGN) harbor a super-massive black hole at their core surrounded by an accretion disk. Little is known about the interaction between the accretion disk and the black hole, an interaction that produces powerful beamed jets of highly-energetic particles and radiation. The spectrum of this radiation is a strong indicator of the acceleration mechanisms involved. Combined VHE, X-ray, and UV spectra can test and help to tune current models of the acceleration processes of active galaxies. The goals of this award are to improve the VERITAS gamma ray detection algorithms and to use the improved algorithms to study the acceleration mechanisms in AGN and pulsars. Under Broader Impacts, undergraduate students will be given broad exposure to the science while working on a focused and tractable research project suitable for a senior thesis. This grant will bring the expertise of two senior personnel to all 165 physics majors and support two student research projects each year. The PI will connect with middle school teachers through the Center for Excellence In Science and Mathematics Education (CESaME) to develop supplements that can be used in 6 and 8th grade curricula where Science and Astronomy are taught.

提案编号：0758085研究机构：加州理工州立大学基金会NSF研究项目：物理-粒子天体物理学实验室：Christiansen，Jodi L.标题：RUI：VERITAS观测的TeV伽马射线和脉冲星的分析 摘要RUI基金将为圣路易斯奥比斯波的加州理工州立大学带来天体物理学的经验。VERITAS，甚高能辐射成像望远镜阵列系统，位于亚利桑那州南部的维普莱天文台基地营地，是一个成像大气切伦科夫望远镜阵列，旨在探测甚高能（VHE）伽马射线（100 GeV？50 TeV），在地球上淋浴？的大气层。活动星系（AGN）的核心有一个超大质量黑洞，周围环绕着一个吸积盘。人们对吸积盘和黑洞之间的相互作用知之甚少，这种相互作用产生了高能粒子和辐射的强大光束射流。这种辐射的光谱是所涉及的加速机制的一个强有力的指标。结合VHE，X射线和紫外光谱可以测试和帮助调整活动星系加速过程的当前模型。该奖项的目标是改进VERITAS伽马射线探测算法，并使用改进后的算法研究活动星系核和活动星系核中的加速机制。在更广泛的影响下，本科生将广泛接触科学，同时致力于适合高级论文的重点和易于处理的研究项目。该补助金将为所有165个物理专业带来两名高级人员的专业知识，并每年支持两个学生研究项目。PI将通过科学与数学教育卓越中心（CESaME）与中学教师建立联系，以开发可用于教授科学和天文学的6年级和8年级课程的补充材料。
