Peculiar Velocities of Galaxies Just Beyond the Local Group

In physical cosmology, peculiar velocity refers to the components of a galaxy's velocity that deviate from the Hubble flow. According to Hubble's Law, galaxies recede from us at speeds proportional to their distance from us. Galaxies are not distributed evenly throughout observable space, but are typically found in groups or clusters, where they have a significant gravitational effect one on another.

WebIn practice the velocities of galaxies have an additional 'peculiar velocity' that deviates from the Hubble Flow. It has long been supposed that the expansion of the Universe 'washes out' these perturbations and that after sufficient time all galaxies will join the Hubble Flow. We have found that joining the Hubble Flow is in fact not Webthat prevailed in the mid-1980's was thus one in which the Hubble flow was unperturbed on scales 5000 kms-1.
