标题： Ultra high-energy comic rays: probing the local Universe

摘要： 概述了超高能宇宙射线通过星系间和银河磁场传播的问题。特别强调了在面对介质磁场的不确定性时，将当前事件与潜在源相关联的可能性。只要统计数据足够高，后一个问题可以转化为研究宇宙磁场的强大工具。最后，分析了AGASA合作组织指出的三对事件，作为可能的聚类证据。 显示英文摘要

摘要： A general view is presented on the problem of propagation of ultra high-energy cosmic rays through the intergalactic and galactic magnetic fields. Especial emphasis is given to the possibility of correlating the present events with potential sources face to the uncertainties in the intervening magnetic fields. Given high enough statistics, the latter problem can be transformed into a powerful tool for the study of cosmic magnetic fields. Finally, the three pairs of events pointed out by the AGASA collaboration as a possible evidence for clustering are analyzed.
