Description
In this talk, I will discuss how gravitational weak lensing data can be leveraged to calibrate the masses of galaxy clusters. The South Pole Telescope (SPT) survey detects clusters via the thermal Sunyaev-Zel'dovich (SZ) effect, but this method does not yield direct mass measurements. Gravitational weak lensing provides a complementary approach, enabling accurate mass estimations that are essential for deriving robust cosmological constraints based on galaxy cluster abundance. I will outline the methodology used in the latest SPTxDES analysis, conducted by our team at LMU, to achieve precise mass calibration through weak lensing.
