Purpose: to obtain new knowledge about the nature of gamma sources on the basis of their multiwave research with a decisive contribution to the newly created ST array of Cherenkov telescopes. Research methods: monitoring photometric observations of active galaxy nuclei (ANN) from the STA list in the optical range; search for the correlation of changes in brightness between the optical and gamma ranges by analyzing the brightness curves in the observed SNF; development of methods for detecting the periodicity and quasi-periodicity of changes in brightness in the NF; calculation of fluxes and spectra of the generated KP gamma and neutrino radiation from ZN magnetar SGR 1900 + 14 and ZN Sail; establishing the distribution of the density of the interstellar medium around galactic gamma sources on maps of their surface brightness in the multi-gamma range; modeling of the generated KP gamma radiation in the sources around the Center of the Galaxy at energies above 100 GeV; calculation by the Monte Carlo method of the optimal layout of the array of tools of the CTA project; software development. Monitoring photometric observations of NPP from the STA list in the optical range were performed using telescopes AZT-8, AZT-14, Zeiss-600 and UBVRI filters of the Johnson / Bessel system. For objects 1ES 1426 + 428; 1ES1011 + 496; PKS 1510-089; BL Lacertae; PKS 1222-216; Mrk 501 constructed and analyzed the brightness curves. For AJG 1ES 1011 + 496, PKS 1510-089, BL Lacertae, PKS 1222 + 216, the variability of their brightness during 2018-2020 with an amplitude from 0.2m to 1m was established. Also, as a result of processing for the studied NPPs, changes in color parameters were recorded in all filters (UBVRI); the correlation of changes of brightness between optical and gamma ranges is revealed.  Product Description popup.authors Izviekova Inna O Vasylenko Volodymyr V.
