I review models for the "inner jet" in blazars, the section that connects the central engine with the radio jet. I discuss how the structure and physics of the inner jet can be explored using millimeter-wave VLBI (very-long-baseline radio interferometry) as well as multiwaveband observations of blazars. Flares at radio to gamma-ray frequencies should exhibit time delays at different wavebands that can test models for both the high-energy emission mechanisms and the nature of the inner jet in blazars.
我回顾了耀变体中“内喷流”的模型,这是连接中央引擎和射电喷流的部分。我讨论了如何利用毫米波甚长基线射电干涉测量法(VLBI)以及耀变体的多波段观测来探索内喷流的结构和物理特性。从射电到伽马射线频率的耀斑在不同波段应表现出时间延迟,这可以检验高能发射机制和耀变体中内喷流性质的模型。
