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.

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。由于恒星在其生命过程中保留了化学指纹，并且长时间保存了运动学信息，因此研究现在的恒星可以告诉我们过去的情况。这项提议的主要目的是解开星星化学指纹中包含的信息，并利用它来在我们对银河系等星系形成的理解方面取得重大进展。在追求这一目标，我将汇集信息，从观察和建模技术，我已经开发。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动机建模。关键的见解将通过比较矮星系和银河系的化学指纹来实现。这一建议是对莱布尼茨-波茨坦天体物理研究所科学方案的补充，将大大受益于该主办机构的专业知识。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。
