Testing Cosmology with the Dark Energy Survey and the Legacy Survey of Space and Time We are at a crossroads for observational cosmology. Will the standard cosmological model suffice to account for current and forthcoming observations, or do we need a modified or new model? The Dark Energy Survey is in its final stages, and there is the opportunity to contribute to its ultimate measurements of cosmological parameters, using a combination of galaxy clustering and gravitational lensing. In this PhD project, the student will begin by joining the DES effort to measure cosmology in the DES Y6 key project. After this apprenticeship, the student will use their growing experience in measuring cosmological quantities with clustering and lensing to make some of the first cosmological measurements in the Dark Energy Science Collaboration, within the Legacy Survey of Space and Time with the Vera Rubin Observatory.

通过黑暗能源调查以及对时空的传统调查测试宇宙学，我们正处于观察宇宙学的十字路口。标准宇宙学模型是否足以说明当前和即将进行的观察结果，还是我们需要修改或新模型？黑暗能源调查处于最终阶段，有机会使用星系聚类和重力镜头的组合，为宇宙学参数的最终测量做出贡献。在这个博士学位项目中，学生将加入DES在DES Y6关键项目中衡量宇宙学的努力。在这一学徒制之后，学生将在与Vera Rubin天文台的时空调查中，在黑暗能源科学合作中，通过聚类和镜头来测量宇宙学的经验，以进行黑暗能源科学合作的一些宇宙学测量。
