In this review paper, we present the main aspects of high-energy cosmic neutrino astrophysics. We begin by describing the generic expectations for cosmic neutrinos, including the effects of propagation from their sources to the detectors. Then we introduce the operating principles of current neutrino telescopes, and examine the main features (topologies) of the observable events. After a discussion of the main background processes, due to the concomitant presence of secondary particles produced in the terrestrial atmosphere by cosmic rays, we summarize the current status of the observations with astrophysical relevance that have been greatly contributed by IceCube detector. Then, we examine various interpretations of these findings, trying to assess the best candidate sources of cosmic neutrinos. We conclude with a brief perspective on how the field could evolve within a few years.

中微子望远镜和高能宇宙中微子

在这篇综述文章中，我们介绍了高能宇宙中微子天体物理学的主要方面。我们从描述宇宙中微子的一般期望开始，包括从它们的源到探测器的传播的影响。然后，我们介绍了当前中微子望远镜的工作原理，并检查了可观测事件的主要特征（拓扑）。在讨论了主要的背景过程之后，由于伴随宇宙射线在地球大气中产生的次级粒子的存在，我们总结了IceCube探测器对天体相关性观测的当前状态。然后，我们检查了这些发现的各种解释，试图评估宇宙中微子的最佳候选来源。
