A search was made for observations in the radio range of galaxies in the GABRIELLE catalog according to the VLA radio telescope array database; 2. The analysis of radio data of catalog galaxies is carried out for the purpose of allocation of radio structures which testify to possible existence of double system of supermassive black holes in an active galactic kernel (AGN). A sample of AGN candidates for such systems was created; 3. The calculation of successive fusion of three supermassive black holes in the galaxy NGC 6240 using different numbers of dynamic particles (N = 67,000, 135,000, and 270,000 and 540,000) was performed. The evolution of the binary system of black holes of intermediate mass in the galaxy NGC 205 was also modeled.Within the second stage of 2021 of the project "Astrophysical Relativistic Galactic Objects (ARGO): the life path of active nuclei" for the first time the following results were obtained:1.
