3 Results In Figs. The time evolution of the luminous matter for model 1. Views from the z , x and y axes are given. The time evolution of the luminous matter for model 5. Views from the z , x and y axes are given.
Error bars are smaller than the symbol size.
The scaling of dynamical friction with the satellite mass causes the merger times to significantly increase as the satellite mass decreases. The merger affects the structure of the main galaxy in several ways. Transient spiral patterns, warps and non-axisymmetrical structures appear in the disk of the main galaxy. We address those in Sect. We first focus on the structural parameters of the bulge.
