Creating Galaxies on a PC

摘要

It is shown that galactic simulation does not require a supercomputer. The capacity of new PCs is enough to simulate an N-body system With the number of bodies sufficient to see a Galaxy formation from chaos to a disk with a Spiral galactic structure. Naturally, simula- Tions with millions of bodies realized on paral- Lel supercomputers provide more realistic im- Ages. However, the number of bodies is not a Crucial factor if rather qualitative results are Expected.
