Simulating dwarf-dwarf galaxy flyby interactions
This thesis presents the N-body simulation results for the interaction between two equal mass dwarf galaxies. We studied how flyby interactions can cause a different level of disturbance on the dwarf galaxies with the help of four different simulations and measured the departure from their equilibrium state during the interactions. We performed the simulations using N-body code ChaNGa. Initially, we make sure that the interacting galaxies are in an equilibrium state separated by 100 kpc. We established the motion of one galaxy towards another galaxy, which is at rest. We designed the interactions to be increasingly strong by setting the components of velocity and finally we studied the distortion on the galaxies by using Fourier analysis looking at modes m = 1 and m = 2. This analysis allowed us to determine the minimum tidal force required for galaxy distortion.
