超高能宇宙射线的起源与传播

Ultra High Energy Cosmic Rays: origin and propagation

Todor Stanev

摘要:

我们讨论了理解宇宙中最高能量粒子-高能宇宙射线(UHECR)起源的基本困难。很难想象它们被加速的来源。由于UHECR在从源到我们的传播中的强烈衰减,这些源应该离我们宇宙学上的距离很短,但目前还没有确定。我们还提供了最新的实验结果,包括在本次会议上报告的信息,并将它们与UHECR起源的模型进行比较。

英文摘要:

We discuss the basic difficulties in understanding the origin of the highest energy particles in the Universe - the ultrahigh energy cosmic rays (UHECR). It is difficult to imagine the sources they are accelerated in. Because of the strong attenuation of UHECR on their propagation from the sources to us these sources should be at cosmologically short distance from us but are currently not identified. We also give information of the most recent experimental results including the ones reported at this conference and compare them to models of the UHECR origin.
