Abstract: |
Merging processes of satellite galaxies with the parent galaxy lead to a dynamical heating of the disk. Since the energy of the satellite goes into different channels (dynamical friction with the dark halo, radial expansion or contraction of the disk, inclining the disk, and heating of the disk) it is necessary to use detailed numerical computations for a quantitative analysis of the disk heating process. Up to now numerical simulations cannot follow the evolution of the internal structure of thin disks due to artificial heating and resolution problems. With our particle mesh code SUPERBOX we are now able to compute the galaxy-satellite interaction with 107 particles in a mesh of 10243. First simulations show the efficiency of the code for the analysis of the evolution of thin disks. |
