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…
Cosmological Studies from HSC-SSP Tomographic Weak Lensing Peak Abundances
Xiangkun Liu, Shuo Yuan, Chuzhong Pan +3
We perform weak lensing tomographic peak studies using the first-year shear data from Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP) survey. The effective area used in our an…
Cosmological studies from tomographic weak lensing peak abundances and impacts of photo-z errors
Shuo Yuan, Chuzhong Pan, Xiangkun Liu +2
Weak lensing peak abundance analyses have been applied in different surveys and demonstrated to be a powerful statistics in extracting cosmological information complementary to cos…
The Correspondence between Convergence Peaks from Weak Lensing and Massive Dark Matter Haloes
Chengliang Wei, Guoliang Li, Xi Kang +4
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…
