活动星系核（AGN）是高能γ射线源，也被认为是高能宇宙线和中微子源的候选者。我们提出并讨论了离子加速及其与物质和辐射相互作用导致高能中微子产生的各种模型。我们认为中微子的生产机制，在喷气大声和喷气安静AGN，集中在磁盘和日冕附近的中央黑洞，喷流区域，磁化周围的AGN的环境。冰立方合作组织已经报告了高能中微子事件，可能来自喷流响亮的AGN TXS 0506+056和喷流安静的AGN NGC 1068。我们讨论了这些观测本身的含义以及全天空中微子强度的起源。
Active Galactic Nuclei (AGN) are sources of high-energy gamma-rays and are considered to be promising candidates to be sources of high-energy cosmic rays and neutrinos as well. We present and discuss various models for ion acceleration and their interactions with matter and radiation leading to high-energy neutrino production. We consider neutrino production mechanisms in both jet-loud and jet-quiet AGN, focusing on disks and coronae in the vicinity of the central black hole, jet regions, and magnetized environments surrounding the AGN. The IceCube Collaboration has reported high-energy neutrino events that may come from both the jet-loud AGN TXS 0506+056 and the jet-quiet AGN NGC 1068. We discuss the implications of these observations themselves as well as the the origins of the all-sky neutrino intensity.
