摘要

最近从炽星TXS 0506+056中发现了相关的γ射线和中微子发射，这再次引起了人们对炽星作为高能中微子源的兴趣，其中可能的中微子发射涉及炽星喷流中的强子加速。在这篇综述中，我们总结了近期对炽星的多波长和中微子观测的进展。我们重点讨论了目前在轻子和强子模型中对蓝星发射过程的理解。未来结合电磁和中微子测量的多信使观测将有助于我们约束蓝星发射模型，并理解高能γ射线和中微子的起源。

Progress in multi-messenger observations and emission models of blazars

The recent hint of correlated $γ$ -ray and neutrino emission from the blazar TXS 0506+056 has renewed interest in blazars as the source of high-energy neutrinos, in which the possible neutrino emission involved hadronic acceleration in the jet of blazars. In this review, we summarize the recent advances in the multi-wavelength and neutrino observations of blazars. We focus on the discussion of the current understanding of blazar emission processes in the leptonic and hadronic model. The future multi-messenger observations combining electromagnetic and neutrino measurements will help us to constrain blazar emission models and understand the origins of the high-energy $γ$ -rays and neutrinos.
