介绍了俄歇天文台的多信使能力。介绍了寻找超高能中微子、光子和中子的技术和性能。一些最相关的结果进行了审查，如严格的上限，被放置到一个通量的扩散宇宙成因中微子和光子，放置在中微子发射的紧凑的二进制合并，LIGO和处女座在其第一次和第二次观测运行期间检测到的界限，以及搜索高能量光子和中子从银河系中心，约束假定的银河系PeVatron的属性，由H.E.S.S.协作本文还讨论了超高能宇宙线与高能天体物理中微子或由它们的电磁辐射加权的特定源群之间的方向相关的观测。它们构成了旨在确定高能宇宙射线来源的额外多信使方法。
An overview about the multi-messenger capabilities of the Pierre Auger Observatory is presented. The techniques and performance of searching for Ultra-High Energy neutrinos, photons and neutrons are described. Some of the most relevant results are reviewed, such as stringent upper bounds that were placed to a flux of diffuse cosmogenic neutrinos and photons, bounds placed on neutrinos emitted from compact binary mergers that were detected by LIGO and Virgo during their first and second observing runs, as well as searches for high energy photons and neutrons from the galactic center that constrain the properties of the putative galactic PeVatron, observed by the H.E.S.S. collaboration. The observation of directional correlations between ultra-high energy cosmic rays and either high energy astrophysical neutrinos or specific source populations weighted by their electromagnetic radiation are also discussed. They constitute additional multi-messenger approaches aimed at identifying the sources of high energy cosmic rays.
