用费米大面积望远镜测试天体粒子物理学

Testing astroparticle physics with the Fermi Large Area Telescope

Aldo Morselli

摘要:

我们今天对宇宙的理解包括压倒性的观测证据,证明存在一种难以捉摸的物质形式,通常被称为黑暗。虽然已经发展了许多理论来描述它的性质,但实际上对它的性质知之甚少。自2008年发射以来,费米伽马射线太空望远镜上的大面积望远镜已经探测到了迄今为止数量最多的伽马射线,在20 MeV-300 GeV的能量范围内,电子+正电子在7 GeV- 1 TeV的范围内。这个令人印象深刻的统计数据使人们能够对暗物质进行非常灵敏的间接实验搜索。我将介绍这些搜索的最新结果。

英文摘要:

Our understanding of the Universe today includes overwhelming observational evidence for the existence of an elusive form of matter that is generally referred to as dark. Although many theories have been developed to describe its nature, very little is actually known about its properties. Since its launch in 2008, the Large Area Telescope, onboard the Fermi Gamma-ray Space Telescope, has detected by far the greatest number ever of gamma rays, in the 20MeV 300GeV energy range and electrons + positrons in the 7 GeV- 1 TeV range. This impressive statistics allows one to perform a very sensitive indirect experimental search for dark matter. I will present the latest results on these searches.
