The Highest Energy Astroparticle Physics

该奖项将资助芝加哥大学参与皮埃尔·奥杰天文台和相关粒子天体物理学。天文台的目的是发现有史以来观测到的最高能量粒子的起源，并研究它们的相互作用。它位于阿根廷的马拉格，观测能量从10^17 eV到10^20 eV以上的宇宙射线。芝加哥小组在观测站元件的设计和安装、在线软件的开发、监测功能、数据分析、谱、各向异性和簇射性质结果对寻找高能宇宙射线源（UHECR）的影响等方面做出了重要贡献。这些包括通过空间传播的影响，银河系和河外磁场的作用，以及用UHECR和中微子测试基础物理的可能性。UHECRs的理论和唯象学研究以及俄歇数据对多波长和多信使粒子天体物理学的影响与观测和数据分析的整合，极大地有利于研究目标和博士后和学生的培养。广泛影响：最高能量粒子起源的发现将影响粒子天体物理学。该观察站对地球仪从阿根廷到越南的公众教育和外联活动产生了重大影响。与俄歇游客中心、马拉格天文馆和阿德勒天文馆合作，芝加哥的努力将通过促进最高能量阵雨的3D和2D可视化、其探测方法和可能的宇宙起源来扩大公众影响，加强公众宣传工作的物理学和天体物理学内容的深度。他们将扩大与美国自然历史博物馆合作开发的《科学通报》视频的覆盖范围。

This award will fund the participation of the University of Chicago in the Pierre Auger Observatory and related particle astrophysics. The Observatory is designed to discover the origin of the highest energy particles ever observed and to study their interactions. Located in Malargue, Argentina, it observes cosmic rays with energies from about 10^17 eV to above 10^20 eV. The Chicago group has made essential contributions to the design and installation of observatory elements, to the development of the online software, to monitoring functions, to the data analysis, to implications of the spectrum, anisotropy, and shower properties results for finding the sources of ultrahigh energy cosmic rays (UHECRs). These include the effects of propagation through space, the role of galactic and extragalactic magnetic fields, and the possibility of testing fundamental physics with UHECRs and neutrinos. The integration of the theoretical and phenomenological studies of UHECRs and the implications of Auger data to multi-wavelength and multi-messenger particle astrophysics with the observations and data anlysis into a single effort has greatly benefited both the research goals and the training of postdocs and students.Broad Impacts: The discovery of the origin of the highest energy particles would impact particle astrophysics. The Observatory has a major impact on public education and outreach across the globe: from Argentina to Vietnam. In collaboration with the Auger Visitors Center, the Malargue Planetarium, and the Adler Planetarium, the Chicago effort will enlarge the public reach and strengthen the depth of physics and astrophysics content of the public outreach efforts by promoting the 3D and 2D visualizations of the highest energy showers, their detection methods and possible cosmic origins. They will expand the reach of the Science Bulletin video developed in collaboration with the American Natural History Museum.
