| 摘 要： | 基于均匀同步自康普顿模型,用双幂率电子谱分布对Fermi-LAT观测到的有高能辐射的TeV Blazar源Mark 421、3C 273、PKS 2155-304的辐射能谱进行计算,并考虑了河外背景光(EBL)的吸收,对谱形做了修正。计算结果与TeV Blazar源Mark 421、3C 273、PKS 2155-304宁静状态下的多波段准同时性观测结果符合得很好,由此得到TeV Blazar源宁静状态下喷流磁场、多普勒因子,电子数密度等几何参数和物理参数。

| Abstract: | Based on the homogeneous Synchrotron-Self-Compton(SSC) model and external background light(EBL) model,we analyze the multi-band data of Fermi-LAT TeV Blazar source Mark 421,3C 273,PKS 2155-304 with dual power electronic spectrum distribution.Our calculation result is entirely accordance with the multi-band simultaneous observed states of TeV Blazar source Mark 421,3C273,PK2155-304 in quiescent state.We finally obtain the TeV Blazar source Jet magnetic field,Doppler factor,electron number density,geometrical... |
