Abstract

The detection of an astrophysical flux of neutrinos in the TeV–PeV energy range by the IceCube Neutrino Observatory has opened new possibilities for the study of extreme cosmic accelerators. The apparent isotropy of the neutrino arrival directions favors an extragalactic origin for this flux, potentially created by a large population of distant sources. Recent evidence for the detection of neutrino emission from extragalactic sources includes the active galaxies TXS 0506+056 and NGC 1068. We here review the current status of the search for the sources of the high-energy neutrino flux, concentrating on its extragalactic contribution. We discuss the implications of these observations for multimessenger studies of cosmic sources and present an outlook for how additional observations by current and future instruments will help address fundamental questions in the emerging field of high-energy neutrino astronomy. Expected final online publication date for the Annual Review of Nuclear and Particle Science, Volume 72 is September 2022.

高能河外中微子天体物理学

冰立方中微子天文台探测到TeV-PeV能量范围内的中微子的天体物理通量，为研究极端宇宙加速器开辟了新的可能性。中微子到达方向的明显各向同性倾向于这种通量的河外起源，可能是由大量遥远源产生的。最近探测到来自河外源的中微子发射的证据包括活动星系TXS 0506+056和NGC 1068。我们在此回顾了高能中微子流源的研究现状，重点关注其在河外的贡献。我们讨论了这些观测对宇宙源多信使研究的影响，并展望了当前和未来仪器的额外观测将如何帮助解决高能中微子天文学新兴领域的基本问题。《核与粒子科学年度评论》第72卷的最终在线出版日期预计为2022年9月。修订后的估计数请参阅http://www.annualreviews.org/page/journal/pubdates。

期刊介绍： The Annual Review of Nuclear and Particle Science is a publication that has been available since 1952. It focuses on various aspects of nuclear and particle science, including both theoretical and experimental developments. The journal covers topics such as nuclear structure, heavy ion interactions, oscillations observed in solar and atmospheric neutrinos, the physics of heavy quarks, the impact of particle and nuclear physics on astroparticle physics, and recent advancements in accelerator design and instrumentation. One significant recent change in the journal is the conversion of its current volume from gated to open access. This conversion was made possible through Annual Reviews' Subscribe to Open program. As a result, all articles published in the current volume are now freely available to the public under a CC BY license. This change allows for greater accessibility and dissemination of research in the field of nuclear and particle science.
