Distance Correlation Methods for Discovering Associations in Large Astrophysical Databases

19 Aug 2013Elizabeth Martinez-GomezMercedes T. RichardsDonald St. P. Richards

High-dimensional, large-sample astrophysical databases of galaxy clusters, such as the Chandra Deep Field South COMBO-17 database, provide measurements on many variables for thousands of galaxies and a range of redshifts. Current understanding of galaxy formation and evolution rests sensitively on relationships between different astrophysical variables; hence an ability to detect and verify associations or correlations between variables is important in astrophysical research...
