Scholarly Poster


The Cosmic Microwave Background Radiation (CMBR) represents the first light to travel in the universe and offers the strongest evidence for the Big Bang theory to date. While scientists have measured this radiation using a Hierarchical Equal Area isoLatitude Pixelization scheme on the sphere, these “HEALPix” points are not well suited for the fast algorithms necessary for mining CMBR data. By transforming the HEALPix grid to a Cartesian grid in a way that preserves crucial symmetry and periodicity, we develop more accurate algorithms for CMBR analysis. Results illustrating the effectiveness of these algorithms over current methods are presented.
