Аннотация
The future space-based GAMMA-400 gamma-ray telescope will be installed on the Navigator platform of the Russian Astrophysical Observatory. A highly elliptical orbit will provide observations for 7-10 years of many regions of the celestial sphere continuously for a long time ( 100 days). GAMMA-400 will measure gamma-ray fluxes in the energy range from similar to 20 MeV to several TeV and electron + positron fluxes up to similar to 20 TeV. GAMMA-400 will have an excellent separation of gamma rays from the background of cosmic rays and electrons + positrons from protons and an unprecedented angular (similar to 0.01 degrees at E-gamma = 100 GeV) and energy (similar to 1% at E-gamma = 100 GeV) resolutions better than for Fermi-LAT, as well as ground-based facilities, by a factor of 5-10. Observations of GAMMA-400 will provide new fundamental data on discrete sources and spectra of gamma-ray emission and electrons + positrons, as well as the nature of dark matter.
