摘要

利用锥形喷流模型研究了蝎虎天体(BL Lac)1ES 0502+675和平谱射电类星体(FSRQ)PKS 0736+017的多波段辐射并获得模型辐射参数.结果表明,两类天体在锥形喷流模型中的模型辐射参数存在差异:FSRQ的γ射线辐射区、磁场强度和喷流功率比BL Lac大,但其体洛伦兹因子比BL Lac小.

Abstract

The conical jet model was used to study the multi-wavelength radiation of the BL Lac object 1ES 0502+675 and the flat-spectrum radio quasar(FSRQ)PKS 0736+017 and the radiation model pa-rameters were obtained.The results show that there are differences in the radiation parameters of the two types of objects in the conical jet model.The jet power,the γ-ray emitting regions and the magnetic field strength of FSRQ are larger than that of BL Lac.But the bulk Lorentz factor of FSRQ is smaller than that of BL Lac.
