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

用暗能量调查和时空遗留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进行的观测，或者我们是否需要一个改进的或新的模型？暗能量调查已经进入最后阶段，现在有机会利用星系团和引力透镜相结合的方法，为最终的宇宙学参数测量做出贡献。在这个博士项目中，学生将首先加入DES Y6关键项目中测量宇宙学的DES努力。在这个学徒阶段结束后，学生将利用他们在用集群和透镜测量宇宙量方面日益增长的经验，在与维拉·鲁宾天文台的空间和时间遗产调查中，在暗能量科学合作中进行一些首批宇宙学测量。

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.
