标题： Ultra-High-Energy Transient Source Search using IceCube Neutrinos and Pierre Auger Photon Candidates

摘要： 超高能粒子的起源仍然是天体物理学中最深奥的谜团之一。 如果存在附近的超高能粒子瞬变源，我们可能会预期中微子和光子的关联辐射，在时间上和空间上紧密一致地到达。 位于南极的IceCube中微子观测站对来自TeV到EeV能量范围的中微子敏感，而位于阿根廷的皮埃尔·奥格天文台则探测宇宙射线，并具备使用地面和荧光探测器观察超高能光子的能力。 尽管奥格合作组报告的超高能光子候选者与宇宙射线背景一致，但它们提供了一个强有力的机遇来寻找相关的中微子-光子事件。 在本篇贡献中，我们介绍了通过结合IceCube的多味中微子数据与2011年至2017年间奥格探测器的光子候选者来搜索超高能瞬变源的框架。 我们将报告我们期望从该搜索中获得的灵敏度以及可能结果的天体物理意义。 显示英文摘要

摘要： The origins of ultra-high-energy particles remain one of the most profound mysteries in astrophysics. If nearby transient sources of ultra-high-energy particles exist, we might expect correlated emission of neutrinos and photons, arriving in close temporal and spatial coincidence. The IceCube Neutrino Observatory, located at the South Pole, is sensitive to neutrinos from TeV to EeV energies, while the Pierre Auger Observatory, in Argentina, detects cosmic rays and has the capability of observing ultra-high-energy photons using surface and fluorescence detectors. The ultra-high-energy photon candidates reported by the Auger Collaboration, though consistent with cosmic ray backgrounds, provide a compelling opportunity to search for correlated neutrino-photon events. In this contribution, we present the framework to search for ultra-high-energy transients by combining multi-flavour neutrino data from IceCube with photon candidates from the Auger Detector from 2011 to 2017. We will report the sensitivities that we expect to achieve from the search and the astrophysical implications of the possible outcomes.
