Galaxy merger is a violent interaction among galaxies, which can be used to explain the formation of irregular galaxies. However, humans can not observe the entire process of galaxy merger that takes a few giga of years, so we need to model such processes by using numerical simulations. We use the hydrodynamics simulation code, GIZMO to model the processes of galaxy mergers. These virtual galaxies are constructed in the supercomputer, and their input parameters are based on the observational results, We simulate the mergers of two galaxies of different properties such as size, mass, etc. Our goal is to understand the outcome of galaxy mergers by studying its star formation rates, and gas properties. Our simulations can help to understand the observations of exotic galaxies that are likely formed from the mergers.
