由Gamma-Ray引发的阵雨对Cosmic-Ray源的研究

Investigation of Cosmic-Ray Sources with Gamma-Ray Initiated Showers

A. V. Uryson

摘要:

本文提出了一种研究超高能宇宙线源的新方法。该方法是基于对超高能宇宙粒子与宇宙背景相互作用时在河外空间产生的伽马射线辐射的分析。我们已经发现,γ射线发射的强度取决于宇宙射线源的特性,特别是它们的遥远程度和初始粒子能谱。在地球大气层中,宇宙射线引发空气簇射,因此选择量子引发的簇射(不包括来自银道面、伽马射线源等的簇射)。我们可以得到上述源特性。我们推导出量子引发簇射的数量为0或~ 3x 1000,这取决于源参数,在10^14 eV处记录的簇射的典型统计值为~10^8。这种差异足以使用这种方法来研究超高能宇宙射线源。

英文摘要:

A new method of investigating ultra-high energy cosmic ray sources is suggested. The method is based on analysis of gamma-ray emission that is generated in extragalactic space when ultra-high energy cosmic particles interact with cosmic background. We have found that intensity of the gamma-ray emission depends on characteristics of cosmic ray sources, specifically on their remoteness and initial particle energy spectra. In the Earth atmosphere cosmic rays initiate air showers, therefore selecting quanta-initiated showers (and excluding those from the galactic plane, gamma-ray sources, etc.) we can obtain above mentioned source characteristics. We derive that the number of quanta-initiated showers is 0 or ~3x1000 depending on source parameters, typical statistics of showers registered at 10^14 eV being of ~10^8. The difference is large enough to use this method for studying ultra-high energy cosmic ray sources.
