| dc.description | The simple unification scheme of powerful radio galaxies and quasars, based entirely on the orientation dependent effects, has been confronted with the observed radio structures for 152 radio galaxies and 173 steep spectrum quasars. Contrary to the scheme's prediction, the cosmological evolution of geometrical parameters describing the large scale structure of these two types of radio sources are different. Linear size, arm ratio asymmetry and bending are all together stronger evolving with epoch for radio galaxies. Moreover, linear size and bending are more closely correlated with radio luminosity for radio galaxies than for quasars. This supports the supposition that, even if these two AGN classes are intrinsically identical sets of objects in deep interior regions, their large scale structures reveal rather various host environmental conditions which can lead to various classes of objects. | |
