The project aims to contribute to the answer to a fundamental question: how galaxies, including our own, evolved over the Universe's history. The project plans to develop sophisticated spectral models and use them to extract crucial information on star formation, stellar populations, interstellar gas and dust properties from modern galaxy surveys at different cosmic epochs using a consistent framework. These imaging and spectroscopic surveys would be complemented with measurements of the total gas reservoir of galaxies, obtaining a full census of the baryons in galaxies. Together, these may deliver significant insights into how the growth of galaxies, driven by the fuelling, efficiency and outputs of star formation, depends on galaxy properties in the local and distant Universe.

该项目旨在回答一个基本问题：星系，包括我们自己的星系，如何在宇宙的历史中进化。该项目计划开发复杂的光谱模型，并利用这些模型从不同宇宙时期的现代星系调查中提取关于星星形成、恒星种群、星际气体和尘埃性质的关键信息，使用一致的框架。这些成像和光谱测量将与星系总气体库的测量相补充，获得星系中重子的全面普查。总之，这些可能会提供重要的见解，星系的增长，由燃料，效率和星星形成的输出驱动，取决于星系在本地和遥远的宇宙属性。
