4C 34.47是与类星体相关的最大射电源，在其核心中观测到了超光速运动。数据表明，视超光速核心膨胀速度为（2.5 +或- 0.2/h c（h 0 = 100 h km/s Mpc和q 0 = 0.5）。4C 34.47的超光速扩展核心嵌入一个扩展了560/h kpc的双叶射电源中。在相对论性聚束的框架下对4C34.47的超光速性质进行了解释。30个参考文献。
Superluminal motion in the core of 4C 34.47, the largest radio source associated with a QSO, has been detected. The data indicate an apparent superluminal core expansion speed of (2.5 + or - 0.2/h c(h0 = 100h km/s Mpc and q0 = 0.5). The superluminally expanding core of 4C 34.47 is embedded in a double-lobed radio source which is extended by 560/h kpc. Explanation of the superluminal character of 4C 34.47 in the framework of relativistic beaming is considered. 30 references.
