We are members of the Cosmology group at the Institute for Astronomy, University of Hawaii.  This site presents our recent findings on the imprints of super-structures on the Cosmic Microwave Background through the effects of Dark Energy.  The journal paper can be downloaded.

The background image is an example of a Voronoi tessellation. Each cell represents the volume surrounding a galaxy and gives a good measure of the 3D space density. We use the tessellation scheme to find galaxy clusters and voids.
