The work contains both theoretical and observational parts. The usage of multiwavelength properties of AGNs will allow: - The detailed studies of the physical properties of hot and cold gas in the halo of massive elliptical galaxies to build a robust model for the formation and evolution of diffuse gas, as well as to improve understanding of the evolution of the large-scale structure of the universe as a whole; - Investigate the content of the baryon component in the total mass of clusters, groups, and galaxies to construct a more accurate mass function, which in turn will allow a more accurate study of the mass distribution of the universe as a whole; - Apply theoretical feedback models from active galaxy nuclei in clusters, groups, and early-type galaxies to test the effect of active nuclei on intergalactic and interstellar gas; - Create a sample of interacting galaxies. Search for available observations for the obtained sample of studies and on their basis estimate the masses of supermassive black holes by available methods. Obtain estimates of the accretion rate on the SMBH of galaxies and corresponding Eddington luminosity; - Observation of spectral and photometric properties of isolated active galaxy nuclei using optical telescopes. Obtain the value of black hole mass for isolated AGNs, and define the variability based on BVRI filters. Apply the reverberation method to determine the parameters of the central parts of the AGNs. popup.nrat_date 2024-12-09 Close
