用GAMMA-400研究高能gamma-ray
High-energy gamma-ray studying with GAMMA-400
摘要：
地外伽马射线天文学现在是天体物理学、宇宙射线物理学和暗物质性质等领域新知识的来源。发展地外高能伽马射线天文学的下一个绝对必要的步骤是改进伽马射线望远镜的物理和技术特性，特别是角分辨率和能量分辨率。这样的新一代望远镜将是伽马-400。伽马-400是目前正在研制中的伽马射线望远镜，它将与X射线望远镜一起，在~20 MeV ~1000 GeV和3-30 keV的能量范围内，对银河系平面，特别是银河系中心、费米泡、蟹状星云、天鹅座、伽马-400将在高椭圆轨道上长时间连续运行，（在Eγ = 100 GeV时约为0.01°）和能量（在Eγ = 100 GeV时约为1%）的分辨率比费米-LAT以及地面伽马射线望远镜好5-10倍。伽马-400将允许解析来自暗物质粒子湮灭或衰变的伽马射线，识别许多离散源（其中许多是可变的），澄清扩展源的结构，指定漫射发射的数据。
英文摘要：
Extraterrestrial gamma-ray astronomy is now a source of new knowledge in the fields of astrophysics, cosmic-ray physics, and the nature of dark matter. The next absolutely necessary step in the development of extraterrestrial high-energy gamma-ray astronomy is the improvement of the physical and technical characteristics of gamma-ray telescopes, especially the angular and energy resolutions. Such a new generation telescope will be GAMMA-400. GAMMA-400, currently developing gamma-ray telescope, together with X-ray telescope will precisely and detailed observe in the energy range of ~20 MeV to ~1000 GeV and 3-30 keV the Galactic plane, especially, Galactic Center, Fermi Bubbles, Crab, Cygnus, etc. The GAMMA- 400 will operate in the highly elliptic orbit continuously for a long time with the unprecedented angular (~0.01° at Eγ = 100 GeV) and energy (~1% at Eγ = 100 GeV) resolutions better than the Fermi-LAT, as well as ground gamma-ray telescopes, by a factor of 5-10. GAMMA-400 will permit to resolve gamma rays from annihilation or decay of dark matter particles, identify many discrete sources (many of which are variable), to clarify the structure of extended sources, to specify the data on the diffuse emission.
