The Radio-Gamma-Ray Connection: the Radio Properties of Gamma-Ray-Bright Blazars

Abstract
Forty AGN have been detected at high significance level by EGRET in the γ-ray band. Previous studies based on radio observations near or at the times of the EGRET detections suggest that there is a causal connection between individual events in these two wavebands. Here we examine the question of whether the cm-λ and the γ-ray activity are related.
