Energy Spectrum of Very High Energy Gamma-Quanta from Cygnus X-3 in Year 2003
Abstract
The observational data for the Galactic source Cygnus X-3 collected with the SHALON mirror Cherenkov telescope are presented. The Cygnus X-3 binary have been regularly observed since 1995 with the average γ-ray flux F (E > 0.8 TeV) = (6.8 ± 0.7) × 10-13 cm-2 s-1. The flux in year 2003 was (1.79 ± 0.33) × 10-12 cm-2 s-1. Earlier, in 1997, an increase of the flux was also observed.
