Fingers of God is an effect in cosmology that causes clusters of galaxies to be elongated in redshift space, with an axis of elongation pointed toward the observer. It is due to an effect where the peculiar velocities of the galaxies in a cluster associated with the gravity of the cluster by means of the virial theorem change the observed redshifts of the galaxies in the clusters as a deviation from the Hubble Law expansion that is nominally expected.
