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循环：从星系的喂养过程，经过星星形成，到气体从星系流出的过程。这就需要对气体从丝状体穿过晕圈到达星系的流入过程、多相气体介质中星星的形成过程以及高能事件对星系气体含量的影响进行完整的物理描述。这一河外天体物理学领域的项目旨在补充澳大利亚的主要观测工作，如平方公里阵列及其探路者，因为它将提供模拟，对宇宙中的中性气体进行全面的物理描述。
