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…
Void Lensing in Cubic Galileon Gravity
Chen Su, Huanyuan Shan, Jiajun Zhang +6
Weak lensing studies via cosmic voids are a promising probe of Modified Gravity (MG). Excess surface mass density (ESD) is widely used as a lensing statistic in weak lensing resear…
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…
The Ultramarine Simulation: properties of dark matter haloes before redshift 5.5
Qiao Wang, Liang Gao, Cheng Meng
We introduce the Ultramarine simulation, an extremely large -body simulation of the structure formation and evolution to redshift 5.5 at which cosmic reionization was just compl…
PhotoNs-GPU:A GPU accelerated cosmological simulation code
Qiao Wang, Chen Meng
We present a GPU-accelerated cosmological simulation code, PhotoNs-GPU, based on algorithm of Particle Mesh Fast Multipole Method (PM-FMM), and focus on the GPU utilization and opt…
A Hybrid Fast Multipole Method for Cosmological N-body Simulations
Qiao Wang
We investigate a hybrid numerical algorithm aimed at the large-scale cosmological N-body simulation for the on-going and the future high precious sky surveys. It makes use of a tru…
