摘要 从UMRAO数据库中,我们收集了3C279在射电4.8GHz、8GHz和14.5GHz的光变数据,并用功率谱方法和Jurkevich方法对其光变曲线进行分析,发现在3C279的射电光变曲线中存在124.4天的周期性,该周期很可能是由双黑洞系统中轨道驱动的螺旋喷流引起的。 Based on the database of UMRAO, we collected the emission data of 3C 279 at 4. 8 GHz, 8 GHz, and 14. 5 GHz. Using the power-spectrum method and the Jurkevich method,We have analyzed the light curves and found there a period P=124.4 days in the light curves of 3C 279 that is most likely caused by the helical motion of the jet.
