皮埃尔·奥杰合作组织最近的一篇文章将带电宇宙射线的方向与可能的河外发射地点联系起来。这种粒子的方向与发射器的方向的相关性允许约束大尺度磁场B的值。假设B的相干长度λ在1 Mpc和10 Mpc之间的范围内,我们发现B的值在0.3和0.9 nG之间。
A recent article from the Pierre Auger Collaboration links the direction of charged cosmic rays to possible extragalactic sites of emission. The correlation of the direction of such particles with the direction of the emitter allows constraining the value of large-scale magnetic fields B. Assuming for B a coherence length λ in the range between 1 Mpc and 10 Mpc, we find values of B between 0.3 and 0.9 nG.
