A Statistical Analysis of Delta PA for EGRET-Detected AGNs
Abstract
A statistical analysis of position angle differences (Delta PA) between small- and large-scale structures of EGRET-detected AGNs has been made. The results show that gamma -ray quasars have the alignment of radio jets, while gamma -ray BL Lac objects have large Delta PA. This may contribute to a better understanding of different blazar types and of the AGN unification scheme.
