Scientific paper

Apart from the nearest example Cygnus A, to date there have been no spectral studies in X-rays of Faranoff-Riley class ii narrow-line radio galaxies (NLRGs). As a first step we present Rosat and Asca observations of the NLRGs 3C219 and 3C234. Despite their faintness in the Einstein energy range (Fabbiano et al. 1984), unlike Cygnus A these objects are not known to reside in X-ray luminous clusters, nor are they placed at low Galactic latitude. Therefore we can expect to measure the 0.2--10keV continuum and Fe K lines originating from the AGN in each case. 3C234 has been shown to possess an optically hidden broad line region visible only in scattered (polarized) light, while 3C219 is a classical NLRG. We shall relate our X-ray data to the spectral properties of these objects at longer wavelengths, in terms of testing the unified scheme for radio galaxies and quasars.
