Very high energy gamma-ray emission of TeV J2032+4130 object

Abstract

Cygnus Region is known to contain a large number of objects which are bright in all wavelengths including 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 the proximity to well-known microquasar Cyg X-3, is object TeV J2032+4130. This object is still of unresolved nature and is being intensively studied in the different energy ranges. The results of twenty-year observation of TeV J2032+4130 object by the SHALON experiment are presented in this paper. The collected experimental data on fluxes, spectrum shape, and morphology of TeV J2032+4130 can help in the future to determine an object type and to shed light on the source nature.
