Object of research: astrophysical sources of gamma radiation: active nuclei of galaxies, remnants of the Supernova, pulsar-wind nebulae. Purpose: to get new knowledge about the nature of gamma sources on the basis of their multi-wave research with the decisive contribution of the newly created Cherenkov telescope STA array. Research methods: monitored photometric observations of active nuclei of galaxies from the STA-list in the optical range; detecting periodicity (quasi-periodicity) by analyzing the brightness curves in the active nuclei of selected galaxies; calculation of streams and spectra of cosmic rays produced by gamma and neutrino radiation through simulation of physical processes in specific galactic sources. The monitored photometric observations of active galactic nuclei from the STA-list in the optical range are performed using the Johnson / Bezel systems with the telescopes AZT-8, AZT-14, Zeiss-600 and UBVRI filters. For objects 1ES 1426 + 428; 1ES1011 + 496; PKS 1510-089; Mr 421; Mr 501; BL Lacertae; PKS 1222-216; M87; NGC 1275 has been constructed and analyzed by glare curves. The GeV-TeV energy range was investigated in the vicinity of the magnetar SGR 1900 + 14 as a potential source of KPGVE. The model of gamma radiation of this region is proposed, which is in good agreement with experimental data. Expected streams of gamma radiation from one of the closest to the Earth to the remnants of the Sovremennaya Sovrem are calculated. The possibility of registration of localized sources of gamma radiation within the remainder due to the presence of areas of increased gas density due to the evaporation of interstellar clouds behind the shock wave front of the residual is analyzed. It is shown that such sources can be registered with the CTA experiment. The background of baryon sources in the Great Magellanic Cloud is simulated to find the collapse of dark matter with the help of CTA.
