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一些周围的星系中，我们才能分辨和观测单个恒星。因为恒星在其生命周期中保留着化学指纹，而且还会长期保存运动学信息，所以研究今天的恒星可以让我们了解过去。这项提议的主要目的是解开恒星化学指纹中包含的信息，并利用这些信息在我们对银河系等星系形成的理解上取得重大进展。在追求这一目标的过程中，我将把我开发的观测和建模技术的信息汇集在一起。该项目包括研究现有的大型观测，设计新的观测项目，以及对星系形成和演化过程进行完全宇宙学驱动的建模。通过将矮星系的化学指纹与银河系进行比较，将获得关键的见解。这项建议是对波茨坦莱布尼兹天体物理研究所科学项目的补充，并将从该主办机构现有的专业知识中受益匪浅。该项目的结果将包括在即将到来的大型银河系考古调查和超大型望远镜时代解释大数据的基本基础。

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.
