Structure on large scale in the Universe up to the distance of 200 Mpc

Abstract

The distribution of galaxies up to a distance of 200 Mpc (650 million light-years) is flat and shows a structure like a shell roughly centered on the Local Supercluster (Virgo cluster). This result clearly confirms the existence of the hypergalactic large scale structure noted in 1988. This is presently the largest structure ever seen.
