最高能量俄歇事件方向的遥远类星体
A Faraway Quasar in the Direction of the Highest Energy Auger Event
摘要：
俄歇天文台报告的最高能量宇宙射线事件的能量为148 EeV。它不与任何附近（z $<$ 0.024）能够产生这种高能量事件的物体相关。有史以来记录的最高能量事件（由Fly's Eye合作）指向一个具有非常高的射电光度和大法拉第旋转测量的遥远类星体，这一事实引起了我们的兴趣，我们已经为Auger事件寻找了类似的来源。我们发现，俄歇最高能量事件点的类星体具有类似的特性，一个相关的蝇眼事件。我们还发现了最高能量的AGASA事件之一的相同类型的相关性。我们的结论是，到目前为止，这些类型的类星体是俄歇和蝇眼最高能量事件的最佳源候选人。我们讨论了几个外来的候选人，可以达到我们从千兆秒差距的距离。
英文摘要：
The highest energy cosmic ray event reported by the Auger Observatory has an energy of 148 EeV. It does not correlate with any nearby (z$<$0.024) object capable of originating such a high energy event. Intrigued by the fact that the highest energy event ever recorded (by the Fly's Eye collaboration) points to a faraway quasar with very high radio luminosity and large Faraday rotation measurement, we have searched for a similar source for the Auger event. We find that the Auger highest energy event points to a quasar with similar characteristics to the one correlated to the Fly's Eye event. We also find the same kind of correlation for one of the highest energy AGASA events. We conclude that so far these types of quasars are the best source candidates for both Auger and Fly's Eye highest energy events. We discuss a few exotic candidates that could reach us from gigaparsec distances.
