The Virgocentric flow (VCF) is the preferred movement of Local Group galaxies towards the Virgo Cluster caused by its overwhelming gravity, which separates bound objects from the Hubble flow of cosmic expansion. The VCF can refer to the Local Group's movement towards the Virgo Cluster, since its center is considered synonymous with the Virgo cluster, but more tedious to ascertain due to its much larger volume.
