Bulk Motion of Galaxies and Hubble Flow Anisotropy on a Scale of 100 Mpc
Published online by Cambridge University Press: 26 May 2016
Abstract
We study a large-scale bulk motion of thin edge-on spiral galaxies from the RFGC catalogue using a multipole decomposition of velocity field. The quadrupole and octupole components are statistically significant. The first one corresponds to the Hubble flow anisotropy, the second one leads to decrease of modulus of dipole component due to the strong dipole-octupole interaction.
