This project aims to reveal the process of gaseous accretion in interacting galaxies by elucidating the origin and evolution of the Magellanic Stream. The Magellanic Stream is an enormous tail of hydrogen gas extending from the Magellanic Clouds almost fully around the Milky Way. Through unravelling the Magellanic Stream and revealing how it will impact the Milky Way, this project will help understand how galaxies receive new gas to continue their star formation and very existence. The project will use the newly constructed Australian Square Kilometre Array Pathfinder to shed light on the question of how galaxies evolve, one of the highest priority questions in Australian Astrophysics as defined by the Australian Astronomy Decadal Plan.

该项目旨在通过阐明麦哲伦流的起源和演变，揭示相互作用星系中气体吸积的过程。麦哲伦流是一个巨大的氢气尾，从麦哲伦云延伸出来，几乎完全围绕着银河系。通过解开麦哲伦流并揭示它将如何影响银河系，该项目将有助于了解星系如何获得新的气体以继续其星星的形成和存在。该项目将使用新建造的澳大利亚平方公里阵列探路者来阐明星系如何演变的问题，这是澳大利亚天文学十年计划定义的澳大利亚天体物理学中最优先的问题之一。
