... Jets are now detected in up to 70% of a sample of 50 nearby FRII radio galaxies with taken from the 3CR catalogue, the majority of which have been imaged at 8 GHz with the VLA: this represents a significant increase in detection rates over previous systematic jet searches. ... Preliminary attempts to relate jet detection rate to parameters such as the total source luminosity have proved unsuccessful, suggesting a strong environmental influence on jet visibility. ... Brief introduction: what is a jet...
