Galactic seismology: a new window on Milky Way's evolution

该项目旨在研究银河系如何对一个小矮星系通过其平面的通道作出反应。这是由于观测发现了穿越银河系圆盘的大尺度波，以及新的相关超级计算机模拟。该项目预计将在进一步的超级计算机模拟和将预测与盖亚空间使命的新数据进行比较的基础上，在这一领域产生新的知识。 该项目的预期成果包括展示这一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，因为它是在银河系考古学领域。

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.
