This project will undertake detailed observations to determine precisely where and when galaxies formed. This will be done by measuring the amount of star formation in clusters, groups, and isolated galaxies at different epochs. By comparing this evolution with the expected growth of dark matter structures from theory, I will be able to make the important distinction between the internal physics governing a galaxy's evolution and those forces imposed upon it by its surroundings. This will address one of the most important outstanding problems in extragalactic astronomy: understanding how galaxies like the Milky Way formed and evolve over time.

该项目将进行详细的观测，以准确确定星系形成的地点和时间。 这将通过测量不同时期的星团、星系群和孤立星系中星星形成的数量来完成。 通过将这种演化与理论上暗物质结构的预期增长进行比较，我将能够在控制星系演化的内部物理学和周围环境施加给它的力之间做出重要的区分。 这将解决河外天文学中最重要的突出问题之一：了解像银河系这样的星系如何随着时间的推移形成和演变。
