明亮的射电源3C 84在中央10-pc尺度上具有类似CSO的特征,其扩展发射的尺度可达kpc。我们的运动学和同步加速器年龄测量支持,最里面的功能是最近重新启动的活动之前,起源于早期活动的无线电发射已经完全消失形成的CSO。最内层特征的喷流功率在源年龄上的平均速率至少为1044 erg s-1。对中央CSO之外的外部瓣状特征的同步加速器年龄约束表明,该特征起源于101.3 ×105年前的爆发。喷流喷射的推断占空比比从微类星体预期的时间尺度短得多(© 2009 WILEY-VCH Verlag GmbH & Co. KGaA,魏因海姆)
The bright radio source 3C 84 has a CSO-like feature in the central 10-pc scale with extended emissions on scale up to kpc. Our kinematic and synchrotron age measurements support that the innermost feature is a CSO formed by recent restarted activity before the radio emission that originated in the earlier activities has completely faded. The average rate of the jet power of the innermost feature over the source age is at least ∼1044 erg s–1. Synchrotron age constraint for an outer lobe-like feature beyond the central CSO indicates that this feature originates in the outburst from ∼1.3×105 years ago. Inferred duty cycle of the jet ejection is much shorter than the time scale expected from microquasars (© 2009 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
