| Research Abstract |
This study has presented a new trend of galaxy formation theory by revealing the co-evolution between bulge, disk, and black hole in the Milky Way. In particular, the effect of galactic wind from the center on galaxy formation has been extensively examined, which has led to a deep understanding of the formation history of the Milky Way. It turns out that the origin of more than half of bulges in the Universe has been unraveled, In addition, we predict the correlation between the size of bulges and the metallicity gradient over the disks.
