Abstract

Numerical simulations are widely used in the studies of galaxy formation. Here we briefly review their important role in the galaxy formation research, their relations with analytical models, and their limitations as well. Then a progress report is given about our collaboration with a group in the University of Tokyo, including the simulation samples we have obtained, some of the results we have published, and the joint projects which are in progress.
