“…For the study it was used data for 267 nearby radio galaxies identified with elliptical galaxies brighter than 18 t h magnitude (sample1) (Andreasyan & Sol, 1999), and 280 extragalactic radio sources with known position angles between the integrated intrinsic radio polarization and radio axes (sample 2) (Andreasyan et al, 2002). Here there are some results (physical and morphological differences in different classes of extragalactic radio sources) obtained in our study (Andreasyan & Sol, 1999, 2000, Andreasyan et al, 2002, 2013.…”
