Testing Cosmology with Dark Energy Survey and the Legacy Survey of Space and Time

用暗能量调查和时空遗产调查测试宇宙学我们正处于观测宇宙学的十字路口。标准的宇宙学模型是否足以解释当前和即将到来的观测，或者我们需要一个修改的或新的模型？暗能量调查已进入最后阶段，有机会利用星系团和引力透镜的组合，为宇宙学参数的最终测量做出贡献。在这个博士项目中，学生将开始通过加入DES的努力来测量宇宙学在DES Y6的关键项目。在这个学徒之后，学生将利用他们在测量宇宙学数量方面不断增长的经验，通过聚类和透镜来进行暗能量科学合作中的一些第一次宇宙学测量，在维拉鲁宾天文台的空间和时间的遗产调查中。

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.
