Blazar序列及其物理理解

The Blazar sequence and its Physical Understanding

Elisa Prandini, Gabriele Ghisellini

摘要:

在1998年引入的blazar序列试图对blazar的宽带发射特性进行第一次统一的观察,在过去的25年中,blazar序列被广泛用于指导观测以及对这些星系的整体发射的物理解释。在这篇评论中,我们描述了序列的演变,随着观测领域的巨大进步,特别是在伽玛射线波段。还提出了一个新版本的序列上建立TeV检测到的对象。两个极端类的对象(兆电子伏和硬TeV耀变体)包括在讨论中,考虑到它们的相关性,为未来的天文台。最后,介绍了目前对耀变体序列基础的物理认识以及对耀变体序列的主要批评。

英文摘要:

Introduced in 1998 to attempt a first unified view of the broad-band emission properties of blazars, the blazar sequence has been extensively used in the past 25 years to guide observations as well as physical interpretation of the overall emission from these galaxies. In this review, we describe the evolution of the sequence along with the tremendous advances in the observational field, in particular in the gamma-ray band. A new version of the sequence built on TeV-detected objects is also presented. Two extreme classes of objects (MeV and hard-TeV blazars) are included in the discussion, given their relevance for future observatories. Finally, the current physical understanding at the base of the sequence is presented along with the major criticisms to the blazar sequence.
