Investigating possible unification of Seyfert galaxies and blazars in Fermi ‐Large Area Telescope sample

Statistical analyses are invaluable methods used to understand intrinsic emission processes and the unification of extragalactic radio sources. In this paper, we collected radio, X-ray, data blazars from Fermi Large Area Telescope (Fermi-LAT) Seyfert galaxies INTEGRAL/IBIS survey investigated relationship between properties blazar subclasses flat-spectrum quasars (FSRQs) BL Lac objects (BL Lacs). The results show average values that these follow a sequence is indicative probable galaxies-BL Lacs-FSRQs unification. We discovered galaxies, Lacs, FSRQs share similar characteristics in X-ray luminosity (), suggestive fundamental connection while () luminosities least powerful, signifying an evolving structure. From two-dimensional Kolmogorov–Smirnov test, found differ there no significant difference them which implies high-energy emissions may come same mechanism. Significant positive correlations (with coefficient r > 0.60) exist (X-ray ) low-energy components (radio) within whole sample implying form them. These not only consistent with prediction unified scheme for but also have evolutionary link subclasses.
