Onsite Calibration of the Shear-Shear Correlation
Cong Liu, Jun Zhang, Zhenjie Liu
Calibration of the cosmic shear bias is crucial for justifying the cosmological results. However, it is still unclear to what extent calibrations based on simulated galaxy images,…
Calibrating Self-Weighted Shear Estimation via Field Distortion
Zhenjie Liu, Jiarui Sun, Jun Zhang +1
Accurate cosmic shear measurement is the key to fully realize the scientific potential of large scale galaxy surveys. The Fourier\_Quad shear measurement method has been significan…
Joint analysis of small-scale galaxy clustering and galaxy--galaxy lensing from BOSS galaxies
Wenhao Gao, Zhenjie Liu, Zhongxu Zhai +8
We present a joint analysis of galaxy clustering and galaxy--galaxy lensing measurements from BOSS galaxies using a simulation-based emulation method combined with a halo occupatio…
Luminosity-Dependent Assembly Bias of Central Galaxies from Weak Lensing and Clustering
Zhenjie Liu, Hironao Miyatake, Joop Schaye +3
Assembly bias, which is the variation in halo clustering at fixed mass driven by formation history, has long been predicted by numerical simulations but remains difficult to confir…
Dependence of halo properties on central-satellite magnitude gaps through weak lensing measurements
Mingtao Yang, Jiaxin Han, Wenting Wang +9
The magnitude gap between the central and satellite galaxies encodes information about the mass accretion history of a dark matter halo, and serves as a useful observational probe…
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.…
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…
Key drivers of the preference for dynamic dark energy
Zhiqi Huang, Jianqi Liu, Jianfeng Mo +9
Joint analysis of the baryon acoustic oscillations (BAO) measurement by the Dark Energy Spectroscopic Instrument (DESI) first data release, Type Ia supernovae (SNe) of the Dark Ene…
Quasi-2D Weak Lensing Cosmological Constraints Using the PDF-SYM method
Zhenjie Liu, Jun Zhang, Hekun Li +2
Cosmic shear statistics, such as the two-point correlation function (2PCF), can be evaluated with the PDF-SYM method instead of the traditional weighted-sum approach. It makes use…
Halo Properties and Mass Functions of Groups/Clusters from the DESI Legacy Imaging Surveys DR9
Jiaqi Wang, Xiaohu Yang, Jun Zhang +16
Based on a large group/cluster catalog recently constructed from the DESI Legacy Imaging Surveys DR9 using an extended halo-based group finder, we measure and model the group-galax…
Sensitivity tests of cosmic velocity fields to massive neutrinos
Shuren Zhou, Zhenjie Liu, Qinglin Ma +8
We investigate impacts of massive neutrinos on the cosmic velocity fields, employing high-resolution cosmological -body simulations provided by the information-optimized CUBE co…
Update constraints on neutrino mass and mass hierarchy in light of dark energy models
Zhenjie Liu, Haitao Miao
Combining cosmic microwave background (CMB) data from Planck satellite data, Baryon Acoustic Oscillations (BAO) measurements and Type Ia supernovae (SNe Ia) data, we obtain the bou…
Flatness without CMB - the Entanglement of Spatial Curvature and Dark Energy Equation of State
Haoting Xu, Zhiqi Huang, Zhenjie Liu +1
The cosmic spatial curvature parameter is constrained, primarily by cosmic microwave background (CMB) data, to be very small. Observations of the cosmic distance ladder and t…
