The Dependence of Dark Matter Halo Properties on the Morphology of Their Central Galaxies from Weak Lensing
Zhenjie Liu, Kun Xu, Jun Zhang +2
Xu \& Jing reported a monotonic relationship between host halo mass and the morphology of massive central galaxies, characterized by the Sérsic index , at fixed stellar ma…
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…
A Hierarchical PSF Reconstruction Method
Pedro Alonso, Jun Zhang, Cong Liu
Reconstruction of the point spread function (PSF) plays an important role in many areas of astronomy, including photometry, astrometry, galaxy morphology, and shear measurement. Th…
