Abstract

Peculiarities in galaxy morphology are generally accepted to be indications of galaxy interactions and mergers. A study of such peculiarities, therefore, will provide valuable clues to the formation and evolution of galaxies. I have developed a pair of indices, Rotational Asymmetry and Concentration, based on the work of Abraham et al. (1996), to identify galaxies with peculiar morphology. These indices are applied to a large sample of galaxies in the Hubble Deep Field - North for which photometric redshifts have been determined by A. J. Connolly. This powerful combination of deep, high resolution HST data and photometric redshifts allows investigation of trends at redshifts which have been largely inaccessible until now.
