Growing galaxies: a consistent view of star formation across cosmic time

该项目旨在回答一个基本问题：星系，包括我们自己的星系，是如何在宇宙的历史中进化的。该项目计划开发复杂的光谱模型，并利用它们从不同宇宙时期的现代星系调查中提取关于恒星形成、恒星种群、星际气体和尘埃特性的关键信息，使用一致的框架。这些成像和光谱调查将与星系总气藏的测量相辅相成，获得星系中重子的全面普查。总之，这些可能提供重要的见解，星系的增长，由燃料驱动，效率和产出的恒星形成，是如何依赖于星系的性质在本地和遥远的宇宙。

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.
