| Abstract: |
We investigated the formation of elliptical galaxies of different masses using numerical simulations. A three-dimensional TREE N-Body/SPH simulation code has been developed, which includes the dark matter and gas dynamics, radiative cooling, star formation, supernova feedback, and metal enrichment. This code is used to calculate the evolution of a slowly rotating, top-hat over-dense sphere which includes the perturbations expected in a CDM universe. With stellar population synthesis, we analyse the photometric properties of the end-product of the simulation and discuss how the model parameters affect the color-magnitude relation of model elliptical galaxies. We also make an interpretation on the [Mg/Fe] ratios. |
