| Abstract: |
|
The results of almost ten-year observation of Cygnus X-3 point source by SHALON mirror Cherenkov telescope are presented. The galactic source Cygnus X-3, known for more than 10 years as a source with variable intensity < 10−11 − 5 • 10−12cm−2s−1, was regularly observed since 1995 with average gamma-quantum flux F(EO > 0.8TeV ) = (6.8 ± 0.7) • 10−13cm−2s−1. The flux in 2003 was (1.79 ± 0.33) • 10−12cm−2s−1. Earlier, in 1997, an increase in the flux was also observed (1.2 ± 0.5) • 10−12cm−2s−1. The limits on gamma-rays from Cygnus X-3, the source that results stimulated the construction of many new detectors are presented. These upper limits and SHALON fluxes are now more than a factor 100 less than the fluxes originally reported. |
