Forecast of joint analysis of cosmic shear and supernovae magnification from CSST and LSST
Ye Cao, Bin Hu, Ji Yao +1
Cosmic shear and cosmic magnification reflect the same gravitational lensing field. Each of these two probes are affected by different systematics. We study the auto- and cross-cor…
Weak Lensing Reconstruction by Counting DECaLS Galaxies
Jian Qin, Pengjie Zhang, Haojie Xu +4
Alternative to weak lensing measurements through cosmic shear, we present a weak lensing convergence map reconstructed through cosmic magnification effect in DECaLS galaxie…
Assessing Mass Loss and Stellar-to-Halo Mass Ratio of Satellite Galaxies: A Galaxy-Galaxy Lensing Approach Utilizing DECaLS DR8 Data
Chunxiang Wang, Ran Li, Huanyuan Shan +9
The galaxy-galaxy lensing technique allows us to measure the subhalo mass of satellite galaxies, studying their mass loss and evolution within galaxy clusters and providing direct…
MaNGA DynPop -- IV. Stacked total density profile of galaxy groups and clusters from combining dynamical models of integral-field stellar kinematics and galaxy-galaxy lensing
Chunxiang Wang, Ran Li, Kai Zhu +9
We present the measurement of total and stellar/dark matter decomposed mass density profile around a sample of galaxy groups and clusters with dynamical masses derived from integra…
CSST WL preparation I: forecast the impact from non-Gaussian covariances and requirements on systematics-control
Ji Yao, Huanyuan Shan, Ran Li +11
The precise estimation of the statistical errors and accurate removal of the systematical errors are the two major challenges for the stage IV cosmic shear surveys. We explore thei…
DESI and DECaLS (D&D): galaxy-galaxy lensing measurements with 1% survey and its forecast
Ji Yao, Huanyuan Shan, Pengjie Zhang +19
The shear measurement from DECaLS (Dark Energy Camera Legacy Survey) provides an excellent opportunity for galaxy-galaxy lensing study with DESI (Dark Energy Spectroscopic Instrume…
KiDS-1000: cross-correlation with Planck cosmic microwave background lensing and intrinsic alignment removal with self-calibration
Ji Yao, Huanyuan Shan, Pengjie Zhang +11
Galaxy shear - cosmic microwave background (CMB) lensing convergence cross-correlations contain additional information on cosmology to auto-correlations. While being immune to cert…
Forklens: Accurate weak-lensing shear measurement with deep learning
Zekang Zhang, Huanyuan Shan, Nan Li +25
Weak gravitational lensing is one of the most important probes of the nature of dark matter and dark energy. In order to extract cosmological information from next-generation weak…
