Extragalactic archaeology: our galaxy as a rosetta stone of galaxy evolution

该项目旨在测量与银河系明显相似的附近星系的恒星数量。星系的恒星群提供了其整个历史的化石记录，是星系演化的关键窗口。该项目将使用我们银河系中经过充分研究的恒星群作为银河系的罗塞塔石碑来解释来自附近星系的光，揭示它们的化学成分和恒星形成历史。该项目将推进对星系演化的理解，并揭示与我们银河系相似的星系的进化史。这种高度新颖的方法将使澳大利亚能够充分利用其在光学天文学方面的投资，为下一代科学家提供培训和灵感，并保持澳大利亚在尖端光学天文研究方面的国际声誉。

This project aims to measure the stellar populations of nearby galaxies that are apparently similar to the Milky Way. The stellar population of a galaxy provides a fossil record of its entire history and is a key window into galaxy evolution. The project will use the well-studied stellar population of our own galaxy as a galactic Rosetta Stone to interpret the light from nearby galaxies, revealing their chemical compositions and star formation histories. This project will advance understanding of galaxy evolution and reveal the evolutionary history of galaxies that are similar to our own Milky Way. The highly novel approach used will enable Australia to capitalise on its investment in optical astronomy, provide training and inspiration for the next generation of scientists, and maintain Australia’s international reputation for cutting-edge optical astronomy research.
