We propose to study multiwavelengths properties of active galactic nuclei (AGNs) located in different environments, namely, in clusters of galaxies, groups and early-type galaxies, as well as in isolated galaxies. Archival and new observations in the gamma, X-ray, ultraviolet, optical, infrared and radio bands of the electromagnetic spectrum will be used. Multiwavelengths observations of AGNs are an extremely relevant topic in astrophysical research. First of all, an analysis of a statistically-completed sample, that covers a wide range of masses and redshift, different morphological types and environments, different phases of activity, and a wide range of central black hole mass, will be performed. Such an analysis will allow a more accurate study of the nature of AGNs themselves and their impact on clusters, groups, and isolated galaxies in general. Special attention will be conducted to the optical properties of isolated AGNs.
