Scientific paper

The Voronoi tessellation technique is useful for finding galaxy structures in a two-dimensional galaxy distribution. The technique was used on a fragment of the Münster Red Sky Survey and yielded 7280 such structures in an area consisting of 2760 square degrees. The spatial positions of structures containing at least 30 members were compared with those of galaxy clusters from the Abell Corwin Olowin catalogue and resulted in a good correlation for rich objects. Large structures with numerous members frequently consist of smaller substructures.
