关于3C 273喷流活动
摘要
在本文中，我们对3C 273喷流活动在不同时间尺度上的间歇性的可能性进行了讨论。我们提出，3C 273这一原类星体的大尺度射电喷流显著的形态，以及其在主动中心相对侧看不到其对手，可能在重新启动喷流模型的框架下得到解释。特别是，我们提出3C 273射电源本质上是双面的，类似于双双射电星系的类比，但仅倾斜角度与视线夹小角。 In this case, the apparent one-sideness of the kiloparsec-scale radio structure may be due to combined Doppler and time-travel effects alone, if the 3C 273 large-scale jet itself is relativistic and matter-dominated. We also propose, that knotty morphology of the discussed jet, which is observed now additionally at optical and X-ray frequencies, indicates modulation in the jet kinetic power. This, together with the variability of the jet at small (parsec) scales, indicates that the jet activity in 3C 273, and possibly in other similar sources, is variable/modulated/intermittent over many different time-scales.
