DESCRIPTION:Speakers: Nikolay Topchiev (Lebedev Physical Institute)\nFermi
 -LAT has made a significant contribution to the study of high-energy gamma
 -ray diffuse emission and the observation of ~3000 discrete sources. Howev
 er\, one third of all gamma-ray sources (both galactic and extragalactic) 
 are unidentified\, the data on the diffuse gamma-ray emission should be cl
 arified\, and signatures of dark matter particles in the high-energy gamma
 -ray range are not observed up to now. GAMMA-400\, currently developing ga
 mma-ray telescope\, will have the angular (~0.01° at 100 GeV) and energy 
 (~1% at 100 GeV) resolutions in the energy range of 10-1000 GeV better tha
 n the Fermi-LAT (as well as ground gamma-ray telescopes) by a factor of 5-
 10 and observe some parts of the universe (such as Galactic Center\, Fermi
  Bubbles\, Crab\, Cygnus\, etc.) in the highly elliptic orbit (without sha
 ding the telescope by the Earth) continuously for a long time. It will per
 mit to resolve gamma rays from dark matter particles\, identify many discr
 ete sources (many of which are variable)\, to clarify the structure of ext
 ended sources\, to specify the data on the diffuse emission.\n\nhttps://in
