【摘要】 收集了119颗有γ射线噪的Blazar天体样品(97个平谱射电类星体和22个BL Lac天体),用离散相关函数(DCF)方法分析了1GeVγ射线辐射流量(最大值、最小值和平均值)与8·4GHz射电辐射流量之间的相关性.获得的主要结果为:在119个Blazar天体和97个平谱射电类星体中,γ射线辐射流量的最大值以及平均值和射电辐射流量之间有相关性;而γ射线辐射流量的最小值和射电辐射流量之间没有相关性.本文结果表明,γ射线和射电辐射都来自喷流,γ射线很可能产生于同步自康普顿(SSC)过程.更多还原

【Abstract】 In this paper, we collect 119 γ-ray-loud Blazar (97 flat spectrum radio quasars (FSRQs) and 22 BL Lacertae objects (BL Lac)),and investigate respectively the correlation between the γ-ray emission (maximum, minimum, and average data) at 1GeV and the radio emission at 8.4GHz by discrete correlation function (DCF) method. Our main results are as follows: there is good correlation between the γ-ray in high state and average state and radio emissions for the whole 119 Blazar and 97 FSRQs. And there are no correlation between γ-ray emission and radio emission in low state. Our result shows that the γ-rays are associated with the radio emission from the jet, and that the γ-ray emission is likely to have come from the synchrotron self-Compton model (SSC) process in this case.更多还原
