Description

It is suspected that galaxy mergers play an important role in the formation and evolution of galaxies. Their influence is particularly significant in the early universe when galaxies are closer together. Using a set of high-resolution cosmological simulations, we analyze the effect of mergers on the evolution of galaxy structure from an observational perspective. Our method includes modeling the full electromagnetic spectrum of the galaxies in order to visualize the simulations in a realistic way. The subsequent analysis of the resulting morphology allows us to gain a better understanding of the physics that drives galaxy formation. Furthermore, we develop the foundation for a study that will help reveal bias in the recovery of morphological characteristics from actual observations. These results will be used to inform future observational studies of galaxy morphology and evolution.
