我们表明,如果我们假设存在一个无序的宇宙磁场在重组,然后,提供了一个典型的银河系质量对应的共动尺度上的场变化,我们可以解释星系的存在,银河系角动量,和银河系磁场。该理论预测存在当今的星系际磁场B/sub I/G<或大约。=10/sup-9/高斯,在特征长度尺度上变化,约为1 Mpc。
We show that if we assume the existence of a disordered cosmic magnetic field at recombination, then, provided the field varies on a comoving scale corresponding to a typical galactic mass, we can account for the existence of galaxies, galactic angular momenta, and galactic magnetic fields. The theory predicts the existence of a present day intergalactic magnetic field B/sub I/G< or approx. =10/sup -9/ gauss varying on a characteristic length scale approx.1 Mpc.
