基于锥形喷流模型的BL Lac和FSRQ多波段辐射特性研究

Study on the Multi-wavelength Radiation Characteristics of BL Lac Objects and Flat Spectrum Radio Quasars Based on the Conical Jet Model

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.

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 parameters 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,theγ-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.
