论文摘要
通过宇宙的高能光子的传播长度受到$ e^+e^ - $ $ $ $的限制。先前的研究报告了预测和观察到的衰减之间的差异，这表明了新物理学的解释。但是，这些效果以有限数量的观察到来源为主，而许多效果没有显示出任何差异。在这里，我们考虑了这些明显反常物体的天空中的分布，以两种截然不同的方法进行选择：在TEV Blazars删除光谱中距离依赖距离的距离的非物理硬质的研究，以及观察到Bl lac Type物体方向的超高能量空气淋浴的观察。在这两种情况下，通往异常来源的指示遵循了星系的预计局部分布：所有远处的来源，促成异常的遥远来源，都是通过局部细丝来看出的。这匹配了基于光子与细丝磁场中轴突样颗粒的混合而对异常的早期解释的预测。对于超高的能量，可以通过搜索原代伽玛射线来测试这种斧头解释。
The propagation length of high-energy photons through the Universe is limited by $e^+e^-$ pair production on the extragalactic background radiation. Previous studies reported discrepancies between predicted and observed attenuation, suggesting explanations in terms of new physics. However, these effects are dominated by a limited number of observed sources, while many do not show any discrepancy. Here, we consider the distribution in the sky of these apparently anomalous objects, selected in two very different approaches: the study of unphysical hardenings at distance-dependent energies in deabsorbed spectra of TeV blazars, and the observation of ultra-high-energy air showers from the directions of BL Lac type objects. In both cases, directions to the anomalous sources follow the projected local distribution of galaxies: all the distant sources, contributing to the anomalies, are seen through the local filament. This matches the prediction of the proposed earlier explanation of the anomalies based on mixing of photons with axion-like particles in the filament's magnetic field. For ultra-high energies, this axion interpretation may be tested by the search of primary gamma rays.
