论文摘要
Icecube天文台检测TEV-PEV能量范围内中微子的天体物理通量为研究极端宇宙加速器的研究开辟了新的可能性。中微子到达方向的明显各向同性有利于这种通量的胶外形成，可能是由大量遥远来源产生的。最近证明了从阿加拉术来源检测中微子发射的证据包括活跃的星系TXS 0506+056和NGC 1068。我们在这里回顾了寻找高能中微子通量来源的当前状态，集中于其外层面的贡献。我们讨论了这些观察结果对宇宙来源的多通讯研究的含义，并介绍了当前和未来工具的额外观察如何有助于解决高能中微子天文学新兴领域的基本问题。
The detection of an astrophysical flux of neutrinos in the TeV-PeV energy range by the IceCube 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 include 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.
