论文摘要
在这项工作中，我们基于对全银卫星种群的统计估计进行了银河系子困扰的建模。我们介绍了10个子结构模型（Sm $ _ {i} $，i $ \ in $ {1，...，……，10}），具有以下不同参数：a）Subhalos内部概况，b）Subhalos的空间分布，C）Subhalos的质量分布，Subhalos的质量分布，D）subhalos的总数和E）浓度参数。为$τ^{+}τ^{ - } $和$ b \ bar {b} $ nihihilation nihihihihitation通道计算了每个模型中CTA对源的灵敏度曲线。两者都检测到具有CTA的信号（5 $σ$）且没有信号观察的情况下，没有模型可有效访问<$σ$ V>的热值。我们分析了子结构模型引入的系统效应。
In this work, we present a modelling of the galactic sub-clumps based on statistical estimations of the full Milky Way satellite population. We introduce 10 substructure modellings (SM$_{i}$, i $\in$ {1, . . . , 10}) with the following varying parameters: a) subhalos inner profile, b) spatial distribution of subhalos, c) mass distribution of subhalos, d) total number of subhalos and e) concentration parameter. The sensitivity curves of CTA for sources in each model are calculated for the $τ^{+}τ^{-}$ and $b\bar{b}$ annihilation channels. With both detection of a signal (5$σ$) with the CTA and no signal observation, no model was effective in accessing the thermal values of <$σ$ v>. We analyse the systematic effects introduced by the substructures models.
