This project aims to determine the physics behind outflows and inflows at the peak epoch of star-formation in the Universe's history. Surrounding gas is accreted into galaxies along filaments, which fuels the formation of stars. Determining the physics of galaxy flows is key to challenging galaxy evolution models, because they shape the galaxy's morphology, growth and chemical make-up. The project goals are to discover how galaxies are built and evolve by observing and simulating gas flows during their peak of activity.

该项目旨在确定宇宙历史上恒星形成高峰时期流出和流入背后的物理学。周围的气体沿着沿着丝状物被吸积到星系中，这为恒星的形成提供了燃料。确定星系流的物理性质是挑战星系演化模型的关键，因为它们塑造了星系的形态、生长和化学组成。该项目的目标是通过观察和模拟活动高峰期的气体流动来发现星系是如何形成和演变的。
