First application of weak lensing peak steepness statistics to HSC Y1 data: effectively probing halo density profiles
Ziwei Li, Xiangkun Liu, Tianyu Zhang +5
As a new probe, the weak lensing (WL) peak steepness statistics is sensitive to the density profile of halos that encodes important information of baryonic feedback and dark matter…

The convergence peaks, constructed from galaxy shape measurement in weak lensing, is a powerful probe of cosmology as the peaks can be connected with the underlined dark matter hal…
Projection effects of large-scale structures on weak-lensing peak abundances
Shuo Yuan, Xiangkun Liu, Chuzhong Pan +2
High peaks in weak lensing (WL) maps originate dominantly from the lensing effects of single massive halos. Their abundance is therefore closely related to the halo mass function a…
