Outline of Final Research Achievements |
We have constructed merger trees of dark matter halos via N-body simulations using super-computers such as K computer. Taking into account the evolution of baryons, we have developed a new galaxy formation model, which includes many physical processes and formation processes of supermassive black holes within dark matter halos. Active galactic nuclei (AGNs) are activated by accreting gas, and therefore their number density is much lower than that of galaxies. Because our model can compute AGNs in huge volume of the Universe, we create many AGNs enough to discuss their evolution statistically. Thus we estimated their correlation functions and compared them with observations to clarify the evolution of galaxies and AGNs.
