What is written in the stars? A chemical view on the formation of the Milky Way

只有在我们自己的银河系和周围的一些星系中，我们才能分辨和观察单个恒星。因为恒星在其生命过程中会保留化学指纹，也会长期保存运动信息，所以研究现在的恒星可以让我们了解过去的恒星。这项提议的主要目的是解开恒星化学指纹中包含的信息，并利用它在我们对银河系等星系形成的理解方面取得重大进展。为了实现这一目标，我将汇集我所开发的观测和建模技术的信息。该项目涉及对现有大型调查的研究，新观测项目的设计以及星系形成和演化过程的完全宇宙学建模。通过比较矮星系和银河系的化学指纹，将获得关键的见解。该提案是对波茨坦莱布尼茨研究所<s:1>天体物理学研究所科学项目的补充，并将从该主办机构的专业知识中受益匪浅。该项目的结果将为即将到来的大型银河考古调查和超大望远镜时代的大数据解释奠定基础。

Only in our own Milky Way and some surrounding galaxies we can resolve and observe individual stars. Because stars keep a chemical fingerprint during their lives and also preserve kinematical information for long times, studying the present-day stars can teach us about the past. The main aim of this proposal is to unravel the information contained within a star's chemical fingerprint and use it to make significant progress in our understanding of the formation of galaxies like our Milky Way. In pursuing this aim I will be bringing together information from both observations and modelling techniques that I have developed. This project involves the study of large existing surveys, the design of new observational projects and fully cosmologically motivated modeling of galaxy formation and evolution processes. Key insights will be achieved by comparing the chemical fingerprints of dwarf galaxies to the Milky Way. This proposal is complementary to the science programs at the Leibniz-Institut für Astrophysik Potsdam and will benefit greatly from the expertise present at this host institution. The results from this project will consist of fundamental underpinnings for the interpretation of big data in the upcoming era of large Galactic Archaeology surveys and extremely large telescopes.
