When the Pierre Auger Project was proposed in 1998 the stated scientific objective was "to discover and understand the source or sources of cosmic rays with energies exceeding 10**19 eV." A unique partnership of 17 countries has come together to pursue this science. The Pierre Auger Observatory (PAO), completed in June 2008, has accumulated data since January of 2004, and has already yielded results that are the first crucial steps toward those scientific goals. The growing Auger data set will address vital questions in astrophysics and particle physics. The PAO will continue to map the southern sky to strengthen the correlation of the highest energy events with extragalactic sources. A continuously enriched sample of hybrid events with measured longitudinal development will improve our understanding of the cosmic ray composition and features of particle interactions from LHC energies to those well beyond. Resolving the puzzle of apparent excess of muons will benefit from increasing statistics. A precise spectrum measurement in the ankle region with the help of the AMIGA in-fill and the HEAT high elevation telescopes will help determine the transition from galactic to extragalactic sources. Based on hints in the data the search for galactic sources of neutrons and photons may well be fruitful. Finally a search for EeV neutrinos will continue to be of great interest.This award will provide partial funding for the continuing operation of the PAO in Argentina. Collaborating countries fund the operations of the Observatory in proportion to the number of senior authors they have on Auger science publications. The US portion of these operating costs is being shared equally by the National Science Foundation and the US Department of Energy.The study of the highest energy cosmic rays, the most energetic particles in nature, will have broader impacts on the understanding of particle physics at the highest energies as well as astrophysics. The PAO has been a highly successful venue for the training of students and postdocs. The centerpiece of outreach to Malargüe, Argentina, and other nearby communities, the Auger Visitor Center attracts increasing numbers of visitors, typically 6000 each year with the total now exceeding 45,000 since 2001. The Auger collaboration has sponsored two science fairs and has given numerous lectures in the local communities and schools. The daily public release of about 1% of reconstructed events is being used for school projects in many locations.

当1998年提出Pierre Auger项目时，陈述的科学目标是“发现并了解超过10 ** 19 eV的宇宙射线的来源或来源。” 17个国家的独特伙伴关系已经聚集在一起，追求这项科学。皮埃尔·奥格尔（Pierre Auger）天文台（PAO）于2008年6月完成，自2004年1月以来积累了数据，并且已经产生的结果是朝着这些科学目标迈出的第一步。不断增长的螺旋钻数据集将解决天体物理学和粒子物理学中的重要问题。 PAO将继续绘制南部的天空，以加强最高能量事件与乳层外源的相关性。具有测得的纵向发育的连续丰富的混合事件样品将提高我们对从LHC能量到较远的粒子相互作用的宇宙射线组成和特征。解决明显过量的muons的难题将受益于增加的统计数据。借助Amiga填充和热高程望远镜的帮助，在踝部区域进行了精确的光谱测量，将有助于确定从银河系到外层层次源的过渡。根据数据的提示，搜索中子和照片的银河系来源很可能是富有成果的。最后，对EEV神经元的搜索将继续引起人们的极大兴趣。该奖项将为PAO在阿根廷的继续运作提供部分资金。合作国家以与他们在弹臂科学出版物上拥有的高级作者数量成比例的观测站的运作。这些运营成本的美国部分是由国家科学基金会和美国能源部平均分享的。对最高能源宇宙射线，自然界中最有能力的颗粒的研究将对对PAO的粒子物理的理解产生更大的影响，这是对学生和博士学位培训的非常成功的场地。 Auger访客中心是向马拉格古伊，阿根廷和其他附近社区的外展活动的核心，越来越多的游客吸引了越来越多的游客，通常每年有6000个，自2001年以来总数超过45,000。大约1％的重建事件的每日公开发布用于许多地方的学校项目。
