This project aims to investigate how the Milky Way responds to the passage of a small dwarf galaxy through its plane. This is motivated by the observational discovery of largescale waves crossing the Milky Way disc, and by new related supercomputer simulations. The project expects to generate new knowledge in this field, based on further supercomputer simulations and comparison of the predictions with new data from the Gaia space mission. Expected outcomes of the project include a demonstration of the diagnostic power of this new seismological approach to galaxy evolution. The project promises significant benefits in the form of establishing Australia as a leader in Galactic seismology, as it is in the field of Galactic archaeology.

该项目旨在研究银河系对一个小矮星星系通过其平面时的反应。这是由观测到的穿过银河系圆盘的大尺度波的发现以及新的相关超级计算机模拟所推动的。该项目希望在进一步的超级计算机模拟和预测与盖亚太空任务新数据的比较的基础上，在这一领域产生新的知识。该项目的预期成果包括展示这种新的地震学方法对星系演化的诊断能力。该项目承诺将使澳大利亚成为银河系地震学的领导者，就像它在银河系考古学领域一样，带来巨大的好处。
