论文摘要
具有相对论喷气机的活性银河核(AGN)是宇宙中电磁辐射的最强大的天体物理来源。 Blazars是AGN最极端的子类,沿着观察者的视线定向了喷气机。它们的高能量光子发射主导着乳腺外伽马射线的天空,并达到多TEV能量。这表明,Blazars将颗粒加速至非常高的能量。长期以来,人们一直怀疑Blazars也可能将质子加速到极高的能量,因此是宇宙中微子的来源。除了明亮之外,Blazars是极为罕见的物体,是最容易测试的中微子候选源类别之一。最近,触发了几个多理智的监测活动,以响应于从Blazars方向从Icecube Neutminino天文台观察到的高能中微子。在这项贡献中,我总结了这些观察结果的理论解释,并概述了鉴于实验结果,大闪族作为中微子来源的可能作用。
Active galactic nuclei (AGN) with relativistic jets are the most powerful persistent astrophysical sources of electromagnetic radiation in the Universe. Blazars are the most extreme subclass of AGN with jets directed along the line of sight of the observer. Their high-energy photon emission dominates the extragalactic gamma-ray sky and reaches multi-TeV energies. This demonstrates that blazars accelerate particles to very high energies. It has long been suspected that blazars may also accelerate protons to very high energies and thus be cosmic neutrino sources. Being extremely rare objects in addition to being bright, blazars are among the most readily testable neutrino candidate source classes. Several multi-messenger monitoring campaigns have recently been triggered in response to high-energy neutrinos observed with the IceCube Neutrino Observatory from the direction of blazars. In this contribution, I summarise the theoretical interpretation of these observations and give an overview of the possible role of blazars as neutrino sources in light of the experimental results.
