冰立方中微子天文台探测到TeV-PeV能量范围内的中微子天体物理通量，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有利于这种通量的河外起源，可能是由大量遥远的来源产生的。最近发现的河外中微子发射的证据包括活动星系TXS 0506+056和NGC 1068。本文综述了高能中微子流源的研究现状，重点讨论了它在河外的贡献。我们讨论了这些意见的影响，宇宙源的多信使研究，并提出了一个展望如何通过当前和未来的仪器将有助于解决基本问题的新兴领域的高能中微子天文学的额外观测。核与粒子科学年度评论第72卷的预计最终在线出版日期为2022年9月。请访问http://www.annualreviews.org/page/journal/pubdates了解修订后的估计数。
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.
