论文摘要
皮埃尔螺旋钻天文台是运行中最大的Astroparpicle实验。与带电的超高能（UHE）宇宙射线的测量相辅相成，它对检测UHE光子和中微子的检测提供了很好的敏感性。由于光子和中微子通量与带电颗粒的加速机制相关，因此搜索这些中性颗粒会增强对UHE宇宙射线源和瞬态天体物理现象的多个通间者的理解。此外，搜索扩散通量可能会带来有关外来场景的信息，例如银河系中假想超重的暗物质的衰减。在这项贡献中，我们概述了观测站的当前UHE光子和中微子搜索，并讨论了最新结果。我们报告了对UHE光子和中微子弥漫性的严格限制，以及高于1017 eV的点状通量，这在描述了宇宙中最有能力的粒子的源头的理论模型上产生了强烈的限制。
The Pierre Auger Observatory is the largest astroparticle experiment in operation. Complementary to the measurements of the charged ultra-high energy (UHE) cosmic rays, it provides a very good sensitivity to the detection of UHE photons and neutrinos. Since the photon and neutrino fluxes are correlated to the acceleration mechanisms of charged particles, searches for these neutral particles enhance the multi-messenger understanding of UHE cosmic-ray sources and of transient astrophysical phenomena. In addition, searches for diffuse fluxes may bring information about exotic scenarios such as the decay of hypothetical super-heavy dark matter in the Galactic halo. In this contribution, we present an overview of the current UHE photon and neutrino searches at the Observatory and discuss the most recent results. We report on stringent limits to the UHE photon and neutrino diffuse and point-like fluxes above 1017 eV, which lead to strong constraints on theoretical models describing the nature of dark matter candidates and the sources of the most energetic particles in the Universe.
