An analysis of the radio data of the catalog galaxies was performed in order to identify radio structures that indicate the possible presence of a dual system of supermassive black holes in the active galactic nucleus (AGN). A sample of AGN candidates for such systems was created. The successive fusion of three supermassive black holes in the NGC 6240 galaxy using different numbers of dynamic particles (N = 67,000, 135,000, and 270,000 and 540,000) has been calculated. The evolution of the binary system of black holes of intermediate mass in the galaxy NGC 205 was modeled. A sample of about 600 galaxies with features of the active nucleus from the 16th issue of the MaNGA-SDSS survey data was created; on the basis of the specified sample about 140 galaxies in which emissions of substance are observed are found; a positive correlation was found between the emission of matter and the rate of star formation in the galaxy. The spectra of galaxies with double emission lines from the GABRIELLE sample were analyzed in terms of their origin in the leaks of matter in the galaxy. A list of galaxies with active nuclei, which are included in the GABRIELLE sample and are simultaneously classified as radio-loud or radio-intermediate sources (total number - 19 pieces). Namely, it was found that for the list of 19 NPPs there are observations of the XMM-Newton Observatory - for 8 objects, NuSTAR Observatory - 9 objects, Swift / XRT Observatory - for all 19 objects. X-ray spectral analysis of galaxies with active nuclei (AN) included in the GABRIELLE sample, classified as radio-loud or radio-intermediate sources, was performed using observational data from XMM-Newton, NuSTAR and Swift / XRT + BAT observatories.
