Study of the Highest Energy Cosmic Rays with the Pierre Auger Observatory

皮埃尔·奥格天文台（PAO）是一个大型的国际项目，旨在研究Ultra？高能宇宙射线（uhecr）PAO是一项混合实验，它使用大量的表面探测器来测量大面积的空气簇雨到达地球时的足迹，并使用多个荧光望远镜来测量上方空间的空气簇雨。他们已经开始部署一个低能量的延伸来研究银河系到外太空？银河过渡。最新的PAO结果证实了预期已久的GZK由于与微波背景相互作用而在光谱中受到抑制。然而，高能粒子的来源以及它们最初是如何加速的问题是当今粒子天体物理学中最重要的话题之一。一个被怀疑的来源是活动星系核，它是宇宙中已知的能量最高的物体之一。该奖项将资助该研究人员继续参与探测器校准、维护和操作以及PAO数据分析等领域。他的团队雇佣本科生从事探测器的建造、操作、大气监测、数据分析和软件开发。这个小组参与了井？在阿根廷建立PAO外展计划，活动包括准备材料和在访客会上的演讲？s中心、公开演讲、参观学校、科学展览以及为教师和学生开设的课程。

The Pierre Auger Observatory (PAO) is a large International endeavor aimed at the study of Ultra?High Energy Cosmic Rays (UHECRs). PAO is a hybrid experiment with a large array of surface detectors measuring the footprint of an extensive air shower when it reaches the Earth and with multiple fluorescence telescopes measuring the shower in the space above. They have started deploying a low energy extension to study the galactic to extra?galactic transition. The latest PAO results have confirmed the long anticipated GZK suppression in the spectrum due to interactions with the microwave background. However, the sources of the highest energy particles and questions about how they are accelerated in the first place are among the most important topics in particle astrophysics today. One suspected source is Active Galactic Nuclei, which are among the most energetic objects known in the Universe. This award will fund the continued participation of this investigator in the areas of detector calibration, maintenance and operation, and analysis of PAO data. His group employs undergraduate students in detector construction, operation, atmospheric monitoring, data analysis and software development. The group participates in the well?established PAO outreach program in Argentina with activities including the preparation of materials and presentations at the Visitor?s Center, public talks, visits to schools, science fairs, and courses for teachers and students.
