摘要
收集了129个费米选耀变体的多波段准同时性观测数据,利用对数抛物线拟合其能谱分布(SED),获得同步辐射峰值频率(v_s)、同步辐射峰值光度(L_s)及其他相关参数.分析结果表明:L_s与v_s之间有明显的负相关性,支持了耀变体演化遵循从FSRQs到LBLs到HBLs的顺序;星系中心存在小质量黑洞导致L_s-v_s图中呈现低v_s且低L_s的耀变体.
In this paper,we compile the multi-wavelength quasi simultaneous data of 129 Fermi blazars. Using the Logarithmic parabola to fit the spectra energy distribution（SED） of the source, we obtain the peak frequency of synchrotron emission（ vs ）,peak luminosity of synchrotron emis- sion（ Ls ）,and other parameters. The results of correlation analysis indicate that there is a signifi- cantly inverse correlation betweenLs and vs. And this correlation is detailed enough to sustain the blazar evolution sequence along FSRQs→LBLs→HBLs;Moreover, a low-mass black hole in the galaxy center results to a blazar with lowvs and lowLs in theLs- vs frame.
