摘要:

在10度角标度上对7年的Milagro数据进行分析,发现两个局部区域存在超过12 sigma显著性的未知来源。这两个区域都不符合高置信度的伽马射线发射。其中一个区域的能谱与各向同性宇宙射线通量在4.6 sigma的水平不同,并且与具有指数截止的硬谱质子一致,在~10 TeV处最显着过量。这些过度的潜在原因进行了探讨,但没有令人信服的解释被发现。

英文摘要:

An analysis of 7 years of Milagro data performed on a 10-degree angular scale has found two localized regions of excess of unknown origin with greater than 12 sigma significance. Both regions are inconsistent with gamma-ray emission with high confidence. One of the regions has a different energy spectrum than the isotropic cosmic-ray flux at a level of 4.6 sigma, and it is consistent with hard spectrum protons with an exponential cutoff, with the most significant excess at ~10 TeV. Potential causes of these excesses are explored, but no compelling explanations are found.
