利用雅库茨克阵列探测超高频电子回旋共振波的到达方向
Exploring arrival directions of UHECRs with the Yakutsk array
摘要:
分析了雅库茨克阵列探测的超高能宇宙射线(UHECR)的到达方向数据。这项工作是由皮埃尔·俄歇合作最近声称的UHECR和附近活动星系核(AGN)在天球上的位置之间的显着相关性引起的; HiRes合作没有相关性。四个巨射电望远镜阵的观测数据涉及到可能的河外超星系核辐射源,需要进一步深入分析,并对未来的观测数据提出了更高的要求。
英文摘要:
The data on arrival directions of ultra-high energy cosmic rays (UHECRs) detected with the Yakutsk array are analyzed. The work is induced by the recent claim of the Pierre Auger collaboration for the significant correlation found between UHECRs and positions of nearby Active Galactic Nuclei (AGN) on the celestial sphere; and no correlation the HiRes collaboration stands for. Conflicting data of four giant arrays concern possible extragalactic sources of UHECRs and appeal to the profound analysis and to the future data from the Telescope Array/Northern Auger Observatory.
