摘要

人们知道活动星系核的相对论性喷流已经存在了100年。喷流靠近我们视线的耀变体是宇宙中最多变、最极端的物体之一，它从射电到高能伽马射线都有发射。在这篇综述中，我们从观测的角度讨论了耀变体的相对论性喷流，主要目的是讨论如何使用观测来约束理论模型。我们涵盖了从多波长观测到喷气机成像的一系列主题，特别强调了该领域当前的开放性问题。

Relativistic Jets of Blazars

Relativistic jets of active galactic nuclei have been known to exist for 100 years. Blazars with their jet pointing close to our line of sight are some of the most variable and extreme objects in the universe, showing emission from radio to very-high-energy gamma rays. In this review, we cover relativistic jets of blazars from an observational perspective with the main goal of discussing how observations can be used to constrain theoretical models. We cover a range of topics from multiwavelength observations to imaging of jets with a special emphasis on current open questions in the field.
