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

点击翻译按钮获取中文摘要

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.
