Finding Clusters of Galaxies in the Sloan Digital Sky Survey using Voronoi Tessellation
Conference

OSTI ID:786821
The Sloan Digital Sky Survey has obtained 450 square degrees of photometric scan data, in five bands (u', g', r', i', z'), which the authors use to identify clusters of galaxies. They illustrate how they do star-galaxy separation, and present a simple and elegant method of detecting over-densities in the galaxy distribution, using the Voronoi Tessellation.
