| Research Abstract |
We have explored the history of the dark age in the universe from first objects to primordial galaxies by using the Cosmo Simulator FIRST, and then obtained significant results on 1) Formation of first-generation objects and successive star formation, 2) Formation of primordial galaxies and radiative transfer of UV radiation, 3) Cosmological modeling of Lyman alpha emitters, 4) Formation of globular clusters within UV radiation, 5) Merger of massive black holes in primordial galaxies. Besides, a novel method for direct integration of the collisionless Boltzmann equation in Six-dimensional phase space has been developed. In addition, based on the theoretical outcomes, a lot of collaborations on the observations of primeval galaxies have been made, resulting in significant progresses in the study of primordial galaxies.
