来自天体物理源和暗物质的银河系正电子和电子

Galactic positrons and electrons from astrophysical sources and dark matter

Roberto Lineros

摘要:

从最新的实验结果中导出了一个关于电子和正电子宇宙射线起源的非常有趣的谜题。我们模拟这种宇宙射线在一个成功测试的两区传播模型的传播。几个理论上的不确定性--比如与传播有关的--被认为是研究不同类型的电子和正电子源:暗物质湮灭、次级产生和超新星遗迹。

英文摘要:

A very interesting puzzle about the origin of electron and positron cosmic rays is deduced from the latests experimental results. We model the propagation of such cosmic rays in terms of a successfully tested two--zone propagation model. Several theoretical uncertainties -- like ones related to propagation -- are considered to study different types of electron and positron sources: dark matter annihilation, secondary production, and supernova remnants.
