超高能宇宙射线到达方向的分析

Analysis of the Arrival Directions of Ultrahigh Energy Cosmic Rays

A. A. Mikhailov

摘要:

利用雅库茨克、AGASA和SUGAR阵列资料,研究了高能大范围空气簇射(EAS)的到达方向。首次用AGASA和SUGAR列阵资料构造了粒子分布的天球等暴露图。利用Yakutsk、AGASA和SUGAR阵列数据,从银河系本征臂的输入和输出侧探测到了E>4.10^19 eV的宇宙射线的大尺度各向异性。讨论了宇宙线的起源问题。

英文摘要:

The arrival directions of ultrahigh energy extensive air showers (EAS) by Yakutsk, AGASA and SUGAR array data are considered. For the first time, the maps of equal exposition of celestial sphere for the distribution of particles by AGASA and SUGAR array data have been constructed. The large-scale anisotropy of E>4.10^19 eV cosmic rays from the side of Input and Output of the Galaxy Local Arm by Yakutsk, AGASA and SUGAR array data has been detected. The problem of cosmic ray origin is discussed.
