标题： The Pierre Auger Observatory: Contributions to the 39th International Cosmic Rays Conference

摘要： 位于阿根廷拉潘帕阿马里拉的皮埃尔·奥格天文台自2004年以来一直在持续获取数据。 它包括一个覆盖3,000 km$^2$的地表探测器阵列和27台荧光望远镜，旨在探测由超高能宇宙射线引发的广延大气簇射。 2024年对天文台进行了升级，通过增加无线电天线、地表闪烁探测器和埋藏的闪烁探测器阵列来增强现有的水切连科夫探测器。 这份提交给第39届国际宇宙射线会议的论文集，于2025年7月15日至24日在瑞士日内瓦举行， 介绍了皮埃尔·奥格合作组的最新成果，涉及天体粒子物理中的广泛基本问题。 所包含的论文涵盖了超高能宇宙射线的能量谱、质量组成和到达方向的测量，对广延大气簇射中强子相互作用的研究，以及对超高能光子和中微子的搜索。 其他主题还包括无线电探测技术、与太阳相关的现象以及大气事件如ELVES和TGFs。 该列表还包含升级后的探测器AugerPrime的初步结果和性能评估，以及合作组开展的科普和社会参与活动的报告。 显示英文摘要

摘要： The Pierre Auger Observatory, located in La Pampa Amarilla, Argentina, has been continuously acquiring data since 2004. It comprises a surface detector array covering 3,000 km$^2$ and 27 fluorescence telescopes, designed to detect extensive air showers initiated by ultra-high-energy cosmic rays. An upgrade to the Observatory was commissioned in 2024, enhancing the existing water-Cherenkov detectors with additional radio antennas, surface scintillator detectors, and a buried scintillator array. This compilation of contributions to the 39th International Cosmic Ray Conference, held in Geneva, Switzerland (July 15-24, 2025), presents recent results from the Pierre Auger Collaboration, addressing a wide range of fundamental questions in astroparticle physics. The included papers cover measurements of the energy spectrum, mass composition, and arrival directions of ultra-high-energy cosmic rays, investigations of hadronic interactions in extensive air showers, and searches for ultra-high-energy photons and neutrinos. Additional topics include radio detection techniques, solar-related phenomena, and atmospheric events such as ELVES and TGFs. The list also contains first results and performance evaluations of the upgraded detectors, AugerPrime, along with reports on outreach and social engagement initiatives conducted by the Collaboration.
