VHE能量的射电伽辽金

Radio Galaxies at VHE energies

Frank M. Rieger, Amir Levinson

摘要:

银河射电现在已经成为河外天空中一种新的$γ$射线发射源。鉴于它们显著的观测特征,如不寻常的伽马射线光谱或超快VHE变化,它们代表了探索活动星系核的性质和物理学的独特例子。这篇评论提供了一个紧凑的总结,他们观察到的特点,在非常高的$γ$射线能量(VHE; $> 100$ GeV),以及讨论他们可能的物理意义。一个特别的重点是给一个简明扼要的概述有关变量VHE发射的起源,包括最近的事态发展黑洞间隙物理的基本概念。

英文摘要:

Radio Galaxies have by now emerged as a new $γ$-ray emitting source class on the extragalactic sky. Given their remarkable observed characteristics, such as unusual gamma-ray spectra or ultrafast VHE variability, they represent unique examples to probe into the nature and physics of AGN in general. This review provides a compact summary of their observed characteristics at very high $γ$-ray energies (VHE; $> 100$ GeV) along with a discussion of their possible physics implications. A particular focus is given to a concise overview of fundamental concepts concerning the origin of variable VHE emission, including recent developments in black hole gap physics.
