摘要

皮埃尔·奥格天文台,作为世界上最大的空气阵雨实验,提供了前所未有的最高能量中性粒子暴露。自从18年前开始收集数据以来,已经进行了几次对超高能量(UHE, E > 1017 eV)光子和中微子的搜索。来自俄歇数据的UHE光子和中微子的漫射通量的上限是世界上最严格的,严重限制了UHE宇宙射线起源的模型。此外,皮埃尔·奥格天文台通过后续搜索与瞬态事件(如引力波事件)相关的UHE光子和中微子,为当前多信使天文学的努力做出了贡献。介绍了在皮埃尔·奥格天文台数据中寻找超高能光子和中微子的各种活动,并总结了目前的结果。此外,还将讨论未来的展望。

Searching for neutral particles at the highest energies at the Pierre Auger Observatory
The Pierre Auger Observatory, being the largest air-shower experiment in the world, offers an unprecedented exposure to neutral particles at the highest energies. Since the beginning of data collection more than 18 years ago, several searches for ultra-high-energy (UHE, E > 1017 eV) photons and neutrinos have been performed. The upper limits on the diffuse flux of UHE photons and neutrinos derived from Auger data are among the most stringent in the world, severely constraining models for the origin of UHE cosmic rays. In addition, the Pierre Auger Observatory contributes to current efforts in multimessenger astronomy through follow-up searches for UHE photons and neutrinos in association with transient events, such as gravitational wave events. The various activities concerning searches for UHE photons and neutrinos in the data from the Pierre Auger Observatory are presented and the current results are summarized. In addition, future perspectives will be discussed.
