银河系中央区暗物质湮灭产生的γ射线

Gamma rays from Dark Matter Annihilation in the Central Region of the Galaxy

Pasquale Dario Serpico, Dan Hooper

摘要:

在这篇文章中,我们回顾了费米卫星(以前称为GLAST)探测银河系中央区暗物质湮灭的伽马射线的前景,特别是根据最近的天体物理观测和成像大气切伦科夫望远镜的发现。虽然在这部分天空中存在的重要背景在某种程度上限制了费米的发现潜力,但这可以通过利用暗物质湮灭信号相对于天体物理背景的特殊能谱和角分布来缓解。

英文摘要:

In this article, we review the prospects for the Fermi satellite (formerly known as GLAST) to detect gamma rays from dark matter annihilations in the Central Region of the Milky Way, in particular on the light of the recent astrophysical observations and discoveries of Imaging Atmospheric Cherenkov Telescopes. While the existence of significant backgrounds in this part of the sky limits Fermi's discovery potential to some degree, this can be mitigated by exploiting the peculiar energy spectrum and angular distribution of the dark matter annihilation signal relative to those of astrophysical backgrounds.
