Long-term studies of the Cygnus Region and its objects

Abstract

The nineteen-year-long studies of the Cygnus Region at energies 800 GeV -100 TeV by SHALON telescope are presented in this paper. The long-term observations of the Cygnus region centered on Cyg X-3 with the SHALON telescope are revealed the γ-ray emission from the one of nearby object -γCygni SNR, placed at ∼ 2 o from Cyg X-3. The results of γCygni SNR observation since 1995y by SHALON are presented with spectral energy distribution, images and integral spectra at energies 800 GeV -50 TeV. The results of nineteen-year observations of the Cyg X-3 binary at energies 800 GeV -85 TeV, detected by SHALON in 1995y are presented with images and integral spectra. A number of high activity period of Cyg X-3 were detected at energies > 800 GeV during the all observation time. The correlation soft X-ray and TeV energy γ-ray fluxes is traced.
