Ellipticities of Galaxy Cluster Halos from Halo-Shear-Shear Correlations
Zhenjie Liu, Jun Zhang, Cong Liu +1
We report the first detection of the halo ellipticities of galaxy clusters by applying the halo-shear-shear correlations (HSSC), without the necessity of major axis determination.…

Accurate Shear Recovery with Multi-Band Images of Hyper Suprime-Cam
Cong Liu, Jun Zhang, Hekun Li +2
The existing large scale weak lensing surveys typically reserve the best seeing conditions for a certain optical band to minimize shape measurement errors and maximize the number o…

Tele-Correlation: Calibrating Shear-Shear Correlation with Real Data
Zhi Shen, Jun Zhang, Cong Liu +4
Tele-correlation refers to the correlation of galaxy shapes with large angular separations (e.g., degrees). Since there are no astrophysical reasons causing such a correlati…
