Abstract
The Cygnus Region is one of the brightest regions in all ranges of the electromagnetic spectrum and contains a number of potential GeV and TeV emission sources. It includes active star formation regions, pulsars and supernova remnants. Some of the sources have been detected at high and very high energies. One of them discovered due to its proximity to the well-known microquasar Cyg X-3 is the object TeV J2032+4130. This object is still of unresolved nature and is being intensively studied in different energy ranges. The results of twenty-year observations of TeV J2032+4130 by the SHALON experiment are presented in this paper. The collected experimental data on fluxes, spectrum shape and morphology of TeV J2032+413 can help in the future to determine an object type and reveal mechanisms of generation of very high energy emission.
Highlights
The Cygnus Region is one of the brightest areas of the sky in all wavelengths and is known to contain a number of potential GeV and TeV gamma-ray sources
After processing the Cyg X-3 observation data, first by selection criteria associated with Cyg X-3 and with TeV J2032+4130, we found that 8.1% of showers are common for both sources
Very high energy data on the TeV J2032+4130 energy spectrum were obtained in different years with the HEGRA [8], VERITAS [12] and MAGIC [13] groundbased telescopes and with the MILAGRO [6] detector
Summary
The Cygnus Region is one of the brightest areas of the sky in all wavelengths and is known to contain a number of potential GeV and TeV gamma-ray sources. It was detected at very high energies with the Milagro air shower array detector [6] and by imaging atmospheric Cherenkov telescopes Whipple [7], HEGRA [8], SHALON [9,10,11], VERITAS [12] and MAGIC [13].
