We create the initial conditions with the primary galaxy at the center and three satellite galaxies at different distances using DICE software. The mass ratios of the primary and satellite galaxies is 10:1. We simulate the merger using GADGET2 code which includes both collisionless and hydrodynamical simulations. We simulate three different sets of multiple minor mergers which have 0%, 20% and 40% gas in the disk of primary galaxies. We then study the thickening of the disk in the three sets after each merger and evaluate the effect of gas on this. We find that the presence of gas in the disk of the primary galaxy reduces the disk thickening and the increase in the gas percentage furthur reduces it. We also vary the mass ratios of the primary and satellite galaxies and study it's effect on the disk thickening. |
