标题： GRB Sky Distribution Puzzles

摘要： 我们分析宇宙伽马射线暴的天空分布的随机性。这些事件与大质量星系，螺旋星系或椭圆星系有关，因此它们的位置应该追踪大尺度结构，而这种结构可能在宇宙微波背景（CMB）的天空分布波动中显现出来。我们通过CMB峰值和爆发位置分布的马赛克相关映射来检验这一假设，发现这两种信号的分布是相关的，并将这种相关性解释为一种可能的系统效应。 显示英文摘要

摘要： We analyze the randomness of the sky distribution of cosmic gamma-ray bursts. These events are associated with massive galaxies, spiral or elliptical, and therefore their positions should trace the large-scale structure, which, in turn, could show up in the sky distribution of fluctuations of the cosmic microwave background (CMB). We test this hypothesis by mosaic correlation mapping of the distributions of CMB peaks and burst positions, find the distribution of these two signals to be correlated, and interpret this correlation as a possible systematic effect.
