用俄歇天文台寻找大尺度各向异性

Search for large-scale anisotropies with the Auger Observatory

E. Armengaud

摘要:

我们使用两年多的数据从皮埃尔俄歇天文台搜索大尺度上的各向异性在不同的能量窗口。我们在验收中考虑了各种系统学,特别是由于阵列生长和天气变化。我们提出的分析和一致性检查的结果,寻找宇宙射线分布的赤经调制模式。没有观察到这种显著的各向异性。

英文摘要:

We use more than two years of data from the Pierre Auger Observatory to search for anisotropies on large scales in different energy windows. We account for various systematics in the acceptance, in particular due to the array growth and weather variations. We present the results of analyses and consistency checks looking for patterns in the right ascension modulation of the cosmic ray distribution. No significant anisotropies of this kind are observed.
