标题： Ultra-high energy nuclei source in the direction to Virgo cluster

摘要： 该合作组探测到的69个能量E> 55 EeV事件在到达方向上的显著各向异性位于以半人马座A为中心的20度区域内。 不仅两点，而且三点和四点自相关函数都完全被该区域饱和。 此外，在室女座星系团的方向上存在事件的缺失。 如果假设半人马座A附近的过量是由于从室女座星系团转移过来的重核造成的，就可以解释这个异常的20度尺度。 在半人马座A区域和室女座星系团之间的最高能量事件的位置支持了这一观点。 在这种情况下，磁场的大小和方向与银河系模型预期的相似。 天空中存在核素源为对奥格数据进行自洽描述开辟了道路。 显示英文摘要

摘要： The significant anisotropy in the arrival directions of the 69 events with energy E> 55 EeV detected by Pierre Auger collaboration is located in the 20-degree region centered near Cen A. Not only the 2-point, but also the 3-point and 4-point autocorrelation functions are completely saturated by this region. Besides there is an deficit of events in the direction of Virgo cluster. If one assumes that the excess around Cen A is due to heavy nuclei shifted from Virgo, one can explain 20-degree scale of this anomaly. Also location of the highest energy event between the Cen A region and the Virgo cluster supports this idea. Magnitude and direction of the magnetic field is similar in this case to those expected for Galactic models. The existence of nuclei sources in the sky opens the road for a self-consistent description of Auger data.
