A Unified Catalog-level Reanalysis of Stage-III Cosmic Shear Surveys

Understand

Cosmological parameter constraints from recent galaxy imaging surveys are reaching $2-3\%$-level accuracy.

• The upcoming Legacy Survey of Space and Time (LSST) of the Vera C.
• Rubin Observatory will produce sub-percent level measurements of cosmological parameters, providing a milestone test of the $\Lambda$CDM model.
• To supply guidance to the upcoming LSST analysis, it is important to understand thoroughly the results from different recent galaxy imaging surveys and assess their consistencies.
