The project aims is to measure cosmological parameters with novel techniques applied to photo-metric surveys. The student will measure the cross correlation of photmetric surveys with spectroscopic surveys and use these measurements in order to constrain and calibrate the photo metric redshifts from the surveys as well as measuring cosmology. The Student will use ancillary data such as supernovae data and CMB data to enhance the measurements. There will be a thorough Bayesian analysis of the data sets together. The Student will participate to the collaboration work undertaken and contribute with his techniques to the DES, DESI and Euclid projects.

该项目的目的是利用应用于照相测量的新技术测量宇宙学参数。学生将测量光度测量与光谱测量的互相关，并使用这些测量来约束和校准测量的光测红移以及测量宇宙学。学生将使用辅助数据，如超新星数据和CMB数据，以加强测量。将对数据集进行全面的贝叶斯分析。学生将参与所进行的合作工作，并将其技术贡献给DES，DESI和欧几里得项目。
