        主講人簡介: Huanyuan Shan obtained his PhD at NAOC in 2008. Afterwards, Huanyuan spent several years as a postdoc in Peking University, Tsinghua University, EPFL and Bonn University, then he joined in Shanghai Astronomical Observatory as a research professor since 2018. His research focus on weak and strong gravitational lensing.

        Weak gravitational lensing is one of the most powerful techniques to probe cosmology. In this talk, I will first  briefly review the current status of weak lensing surveys. Then I will present the recent cosmological parameter constraints using the Kilo-Degree Survey (KiDS). The results of different statistical quantities can find the S8 tension in comparison with the Planck CMB measurements, indicating that the Universe is more homogeneous than the ΛCDM predicts.
