Co-evolution among Bulge, Disk, and Black Hole, and New Development of Galaxy Formation Theory

该研究揭示了银河系中球、盘和黑洞之间的协同演化，为星系形成理论的发展提供了新的方向。特别是，来自中心的星系风对星系形成的影响已经得到了广泛的研究，这使得人们对银河系的形成历史有了深入的了解。结果表明，宇宙中超过一半的膨胀的起源已经被揭开，此外，我们预测膨胀的大小和盘上的金属丰度梯度之间的相关性。

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.
