New Image Statistics for Detecting Disturbed Galaxy Morphologies at High Redshift

By P. E. Freeman, R. Izbicki, A. B. Lee and J. A. Newman

Abstract

Testing theories of hierarchical structure formation requires estimating the underlying distribution of galaxy morphologies and how that distribution changes as a function of redshift. One aspect of this investigation is the determination of the evolution of the galaxy merger fraction. This is often done by extracting summary statistics (or features) from galaxy images, and associating ranges of statistic values with a priori identified mergers. Commonly used statistics such as the CAS statistics of Conselic
