TeV耀变体的高能伽玛射线辐射研究

摘要

基于双幂率电子谱,考虑了源内极端相对论性电子的逆康普顿散射过程和源外极端相对论性质子与背景光子相互作用(pγ相互作用)对高能伽玛射线辐射能谱的贡献.结合Fermi-LAT最新的观测结果,假定一个合理的电子谱和质子谱,将模型应用于TeV耀变体PKS 2155-304宁静态下的多波段辐射能谱.研究结果表明,上述过程能产生PKS 2155-304宁静态下的多波段辐射能谱,且pγ相互作用产生的次级辐射对高能伽玛射线能谱有明显的贡献.%Based on the double power-law electron spectrum distribution,we consider the inverse Compton scattering of extreme relativistic electron inside the source and extreme relativistic proton outside the source interact with background photons contribution to high-energy γ-rays radiation spectra.With the latest observations of Fermi-LAT,assuming a suitable electron and proton spectra,we apply models to PKS 2155-304 under the quiet state of multi-wavelength spectrum in TeV blazar.The results show that the above processes can produce PKS 2155-304 under the quiet state of multi-wavelength spectrum,andpγinteraction produce secondary emission which have a significant contribution to high-energyγ-rays energy spectrum.
