| dc.description | The lobes of radio-loud AGNs are huge reservoirs of energy so even if the central engine turns off, the radio source is still observable for a substantial amount of time. It is quite obvious, however, that the ignition of a new period of activity can occur before the lobes have faded completely. Restarted activity has been observed in several giant radio galaxies but until recently, it has hardly ever been observed in more compact sources. Here we present an early result of a pilot VLBA programme targeted at compact core-dominated triples. It is found that the milliarcsecond structure of the central components in that type of objects normally take the form of core-jets, which in many cases do not point toward the relic lobes. Therefore, it looks as if the phenomenon of the restarted activity can occur regardless of the source size and it is often accompanied by a repositioning of the central engine. | |
