| 摘 要： | 耀变体甚高能（E100GeV）辐射能谱由于TeV伽玛光子与河外星系背景光光子之间的相互作用而比Fermi-LAT所观测到的伽玛射线能谱更软。基于同步自康普顿模型和河外星系背景光模型,利用高能辐射探测器在GeV和TeV能段对耀变体源3C66A的观测结果,对其红移进行限制。

| Abstract: | The very high energy(E≥100Gev) spectrum of blazars be corrected by the absorption of TeV photons by the Extragalactic Background Light via photon-photon interaction should be softer than the Gamma-ray spectrum observed by Fermi-LAT.In the paper,based on Synchronous self-Compton(SSC) model and the Extragalactic Background(EBL) model,we use observed data by high energy radiation detectors to constrain the redshift of 3C 66A at GeV and TeV range. |
