Dark Matter Search Perspectives with GAMMA-400

Understand

GAMMA-400 is a future high-energy gamma-ray telescope, designed to measure the fluxes of gamma-rays and cosmic-ray electrons + positrons, which can be produced by annihilation or decay of dark matter particles, and to survey the celestial sphere in order to study point and extended sources of gamma-rays, measure energy spectra of Galactic and extragalactic diffuse gamma-ray emission, gamma-ray bursts, and gamma-ray emission from the Sun.

• GAMMA-400 covers the energy range from 100 MeV to ~3000 GeV.
• Its angular resolution is ~0.01 deg(Eg > 100 GeV), and the energy resolution ~1% (Eg > 10 GeV).
• GAMMA-400 is planned to be launched on the Russian space platform Navigator in 2019.
