地面切仑科夫望远镜阵列(IACTs)与空间费米大面积望远镜(Fermi-LAT)的协同观测, 推动了耀变体高能辐射的研究, 特别在耀变体的宽线区结构(BLR)、喷流的物质组成、粒子加速、辐射过程、以及高能宇宙射线起源等方面取得新进展. 同时, 耀变体产生的TeV伽马射线和极高能粒子在传播过程中会与河外背景光(EBL)、微波背景(CMB)及星际磁场(IGMF)发生作用, 可以用TeV耀变体研究河外背景光及星际磁场的强度,以及它对宇宙学的影响. 本文中, 我们简要介绍了TeV耀变体的观测设备、统计性质和相关的研究进展等内容. |

The observation from the ground-based Imaging Atmospheric Cherenkov Telescope arrays (IACTs) and Fermi Large Area Telescope (Fermi-LAT), prompts significantly the study on the high-energy emission in blazars. They involve the structure of the Broad-Line Region (BLR), the content of the jet, particle acceleration, radiation processes, as well as the origin of the high-energy cosmic rays in blazars etc. Based on the interaction of the TeV gamma rays and ultra-high-energy particles from blazars with the Extragalactic Background Light (EBL), Microwave Background (CMB) and Intergalactic Magnetic Field (IGMF), we can explore EBL, CMB and IGMF, as well as the cosmological impact of blazars. In the paper, we introduce briefly the gamma-ray observation equipment, statistical properties and study progresses in TeV blazars. |
