宇宙射线极端分布天文台（CREDO）是一个新成立的全球合作组织，致力于观测和研究宇宙射线（CR）和宇宙射线系综（CRE）：至少两个CR的组，具有共同的主要相互作用顶点或相同的母粒子。CREDO计划包括测试已知的CR和CRE场景，并准备观察意想不到的物理，它也适用于多信使和多任务应用。与CREDO能力完美匹配，CRE可以在经典模型（例如，作为光子-光子相互作用的产物），以及奇异的情形（例如，超重暗物质粒子衰变的结果）。它们的锋面可能在空间和时间上都有很大的扩展，可能包括能量跨越整个宇宙射线能谱的宇宙射线，其足迹至少由两个具有相关到达方向和到达时间的广泛空气簇射组成。由于CRE主要预计将分布在大面积上，并且由于贡献粒子的预期宽能量范围，因此这种CRE探测可能只有在共同使用所有可用的宇宙射线基础设施时才可行，即，作为一个全球扩展的探测器网络。因此，通过这篇评论文章，CREDO合作邀请天体粒子物理学界积极加入或致力于CRE的研究，特别是汇集宇宙射线数据以支持特定的CRE探测策略。
The Cosmic-Ray Extremely Distributed Observatory (CREDO) is a newly formed, global collaboration dedicated to observing and studying cosmic rays (CR) and cosmic-ray ensembles (CRE): groups of at least two CR with a common primary interaction vertex or the same parent particle. The CREDO program embraces testing known CR and CRE scenarios, and preparing to observe unexpected physics, it is also suitable for multi-messenger and multi-mission applications. Perfectly matched to CREDO capabilities, CRE could be formed both within classical models (e.g., as products of photon-photon interactions), and exotic scenarios (e.g., as results of decay of Super-Heavy Dark Matter particles). Their fronts might be significantly extended in space and time, and they might include cosmic rays of energies spanning the whole cosmic-ray energy spectrum, with a footprint composed of at least two extensive air showers with correlated arrival directions and arrival times. As the CRE are predominantly expected to be spread over large areas and, due to the expected wide energy range of the contributing particles, such a CRE detection might only be feasible when using all available cosmic-ray infrastructure collectively, i.e., as a globally extended network of detectors. Thus, with this review article, the CREDO Collaboration invites the astroparticle physics community to actively join or to contribute to the research dedicated to CRE and, in particular, to pool together cosmic-ray data to support specific CRE detection strategies.
