    PR # 31156                                                                   
     AGNs are generally divided into two troups: those associated with and       
      without jets. Ginga discovery of the common presence of a  reflectio       
     n component and an iron emission line in the X-ray spectra of Seyfert       
      galaxies strongly suggests that the central engine is surrounded by        
     a cool accretion disk in the AGNs without jets. On  the other hand, s       
     everal AGNs with jets are found to also exhibit an  iron emission lin       
     e, which suggests that those AGNs have an  accretion disk too.  An im       
     portant question is what physical parameter in the accretion flow cau       
     ses the jets.  In order to see  observational differences between the       
      two groups of AGNs, we  propose systematic study of radio galaxies.
