英文摘要: The spatial distribution of galaxies in our universe is not random, and they demonstrate different alignment patterns on different scales. On the scale of galaxy and galaxy clusters, satellite galaxies tend to be distributed along the major axis of the central galaxy. On large scales, major axis of a central galaxy tends to point towards large scale matter distribution, for example, along the large scale filamentary structure. Even on larger scales, the major axes of different galaxies still have non-negligible correlations. Besides, the angular momentums of galaxies are also correlated with the mass distribution on large scales, with different correlations. This article will review the relative theories and observational developments in galaxies alignment and spatial distribution, it will show that the anisotropic distributions of galaxies on small scales are determined by the non-spherical nature of dark matter halo, and the correlations with large-scale mass distribution are also the natural predictions of cold dark matter theory, and this article also indicates that studies of galaxy alignment help us to understand the physics of galaxy formation and could be used to constrain the nature of dark matter and dark energy.
