Galaxies, dark matter, and dark energy are among the most fascinating mysteries in the Universe. Despite decades of progress, fundamental questions remain open. Because the physics governing cosmic structures is highly nonlinear and complex, large-scale numerical simulations -- run on state-of-the-art supercomputers -- are essential to explore these frontiers.

At the Computational Cosmology Group (CCG, 计算宇宙学研究团组), we build and run cutting-edge cosmological simulations and connect them with the latest observations across the electromagnetic spectrum. Our goal is to deepen our understanding of the cosmos by pursuing questions such as:

• What are the nature and properties of dark matter and dark energy?
• Why does the Universe assemble into a cosmic web?
• How do galaxies form and evolve across cosmic time?
  From the first structures to present-day disks and ellipticals, what roles do feedback, environment, and mergers play?
• What is the formation history of our own Milky Way and Local Group?
  How did its halo, disk, and satellite system come to be, and what can they reveal about fundamental physics?
• ...

To tackle these questions, we combine advanced algorithms, high-performance computing, and multi-wavelength observations, working at the interface of theory, simulation, and observation. We are builders, explorers, and collaborators!
