我们探讨了活动星系核（AGN）中喷流驱动的冲击壳层中加速电子的辐射。针对类星体的强源，将同步辐射和主要产生于类星体核心的各种光子的逆康普顿散射视为辐射过程。我们表明，辐射输出是占主导地位的IC发射紧凑的源（1030 kpc），而同步辐射是更重要的较大的来源。对于强源（Lj~ 1047 ergs ~（-1）），如果源是紧凑的，则费米卫星和现代切伦科夫望远镜（MAGIC、HESS和VERITAS）可以探测到由IC辐射产生的GeV-TeV γ射线。
We explore the emissions by accelerated electrons in shocked shells driven by jets in active galactic nuclei (AGNs). Focusing on powerful sources which host luminous quasars, the synchrotron radiation and inverse-Compton (IC) scattering of various photons that are mainly produced in the core are considered as radiation processes. We show that the radiative output is dominated by the IC emission for compact sources (≲ 30 kpc), whereas the synchrotron radiation is more important for larger sources. It is predicted that, for powerful sources (Lj~ 1047ergs s-1), GeV – TeV gamma-rays produced via the IC emissions can be detected by the Fermi satellite and modern Cherenkov telescopes such as MAGIC, HESS and VERITAS if the source is compact.
