Cosmic Ray天文学

Cosmic Ray Astronomy

Paul Sommers, Stefan Westerhoff

摘要:

宇宙射线天文学试图识别和研究高能宇宙射线的来源。它的独特之处在于它依赖于带电粒子作为信息载体。虽然到目前为止还没有发现高能宇宙射线的离散源,但新一代的探测器正在获得最高能量所需的巨大曝光,其中磁场的偏转最小化,并且来自遥远来源的背景被π介子光生作用消除。本文综述了宇宙线天文学的现状,介绍了宇宙线探测器和分析技术。

英文摘要:

Cosmic ray astronomy attempts to identify and study the sources of ultrahigh energy cosmic rays. It is unique in its reliance on charged particles as the information carriers. While no discrete source of ultrahigh energy cosmic rays has been identified so far, a new generation of detectors is acquiring the huge exposure that is needed at the highest energies, where deflection by magnetic fields is minimized and the background from distant sources is eliminated by pion photoproduction. In this paper, we summarize the status of cosmic ray astronomy, describing the detectors and the analysis techniques.
