GLAST和Milky Way中的暗物质子结构

GLAST and Dark Matter Substructure in the Milky Way

Michael Kuhlen, Jürg Diemand, Piero Madau

摘要:

我们讨论了GLAST探测星系晕中中性伴暗物质湮灭产生的γ射线的可能性。我们已经使用“Via Lactea”,目前最高分辨率的银河系冷暗物质子结构的模拟,量化的贡献subhalos的湮灭信号。假设粒子质量和截面为标准值,我们给出了一个模拟的暗物质湮灭的伽马射线计数的Allsky图。在这种情况下,GLAST应该能够探测到银河系中心和几个单独的subhalos。

英文摘要:

We discuss the possibility of GLAST detecting gamma-rays from the annihilation of neutralino dark matter in the Galactic halo. We have used "Via Lactea", currently the highest resolution simulation of Galactic cold dark matter substructure, to quantify the contribution of subhalos to the annihilation signal. We present a simulated allsky map of the expected gamma-ray counts from dark matter annihilation, assuming standard values of particle mass and cross section. In this case GLAST should be able to detect the Galactic center and several individual subhalos.
