The Symmetry, Color and Morphology of Galaxies in the Hubble Deep Field

Abstract

We present a new method of utilizing the color and asymmetry values for galaxies in the Hubble Deep Field to determine both their morphological features and physical parameters. By using a color-asymmetry diagram, we show that various types of star-forming galaxies (e.g. irregular versus interacting, peculiar galaxies) can be distinguished in local samples. We apply the same methods to the F814W images of the Hubble Deep Field, and show preliminary results indicating that galaxy mergers and interactions are the dominate process responsible for creating asymmetries in the HDF galaxies.Comment: 5 Pages with 1 figure; To appear in "After the Dark Ages: When Galaxies were Young", proceedings of the 9th annual October Astrophysics Conference, ed.
