Research Abstract |
We analyzed many types of galaxies by using the semi-analytic galaxy formation model based on the cold dark matter model that is the currently standard cosmological model.In particular, we investigate the evolution of active galactic nuclei that have central supre-massive black holes as the engine of the activity and the relationship between surrounding galaxies and them. Also, we investigated the relationship between the star formation activity and the infrared radiation from dust, which is made of hevy elements, by modifying the star formation model in the semi-analytic galaxy formation model.
