论文摘要
最近的多通用剂研究为GEV-TEV伽玛射线不透明的高能中微子来源提供了证据。我们介绍了关于活跃星系NGC 1068中中微子和伽马射线之间连接的模型无关的研究，发现中微子很可能来自大约30-100 Schwarzschild Radii的区域。如果中微子是通过摄影子生产过程产生的，尽管如果强核相互作用占主导地位，则尤其是这种情况。我们考虑最有利的中微子生产区域，并讨论冠状，喷气机，风及其与密集材料的相互作用。结果增强了理解冠状区域和流出基础附近耗散机制的重要性。活跃的银河核与近乎埃德丁顿的积聚和潮汐破坏事件之间可能存在联系，因为中微子是在超级质量黑洞附近产生的。
Recent multimessenger studies have provided evidence for high-energy neutrino sources that are opaque to GeV-TeV gamma rays. We present model-independent studies on the connection between neutrinos and gamma rays in the active galaxy NGC 1068, and find that the neutrinos most likely come from regions within about 30-100 Schwarzschild radii. This is especially the case if neutrinos are produced via the photomeson production process, although the constraints could be alleviated if hadronuclear interactions are dominant. We consider the most favorable neutrino production regions, and discuss coronae, jets, winds, and their interactions with dense material. The results strengthen the importance of understanding dissipation mechanisms near the coronal region and the outflow base. There could be a connection between active galactic nuclei with near-Eddington accretion and tidal disruptions events, in that neutrinos are produced in the obscured vicinity of supermassive black holes.
