Examining the morphology of galaxies at high redshifts

Abstract

Irregular galaxies are considered to be results of collisions or close approaches between galaxies. In the local universe, determining the morphological type and collision stage does not pose a problem. However, when it comes to galaxies at high redshifts, determining morphology is non-trivial. In this paper, the morphological parameters used to determine the morphology of galaxies at large redshifts will be summarised and described in detail. The aim of this research is to examine the sensitivity of morphological parameters at different collision stages on galaxies in the Local Universe, so that the most sensitive parameter can be found and later applied to the study of collisions between distant galaxies.
