This project aims to understand the complete cycle of gas in galaxies: from the process of feeding galaxies, going through star formation, to the process of outflowing gas from galaxies. This requires a full physical description of the inflow of gas from filaments going through the halo until reaching galaxies, the process of star formation in a multi-phase gas medium, and the effect energetic events have on the gas content of galaxies. This project in the field of extragalactic astrophysics is designed to complement major observational efforts in Australia, such as the Square Kilometre Array and its Pathfinder, as it will provide simulations with full physical descriptions of the neutral gas in the Universe.

该项目旨在了解星系中气体的完整周期：从喂食星系的过程，通过恒星形成，到星系中流出气体的过程。这需要对通过光环的细丝流入到星系，多相气培养基中的恒星形成过程，以及对星系气体含量的效应事件具有完整的物理描述。该项目中的该项目旨在补充澳大利亚的主要观察努力，例如平方公里阵列及其探路者，因为它将为宇宙中中性气体提供完整的物理描述。
