AKRA 3.0: A matrix-free Inversion Framework for Weak Lensing Mass Mapping and Its Application to DES Y3 Data
Yuan Shi, Pengjie Zhang, Li Cui +2
Weak gravitational lensing mass mapping offers a direct probe of the matter distribution. Accurate reconstruction of mass maps from masked shear catalogs remains challenging due to…
The first AKRA mass map reconstruction from HSC Y1 data
Yuan Shi, Pengjie Zhang, Zhao Chen +4
Weak lensing mass-mapping from shear catalogs faces systematic challenges from survey masks and spatially varying noise. To overcome these issues and reconstruct unbiased convergen…
Proposal to construct the dark-matter-only counterpart of the observed universe combining weak lensing and baryon censuses
Shuren Zhou, Pengjie Zhang
Baryonic effects such as AGN feedback can significantly impact the matter clustering, are harder to model from first principles, and emerge as a severe limiting factor in weak lens…
Cavendish experiment with fast radio bursts on cosmological scales
Shuren Zhou, Pengjie Zhang
A key measure of gravity is the relation between the Weyl potential and the matter overdensity , encapsulated as an effective gravitational constant for…
Meta-Calibration of the Cosmic Magnification Coefficient: Toward Unbiased Weak Lensing Reconstruction by Counting Galaxies
Jian Qin, Pengjie Zhang, Zhu Chen +6
Weak lensing alters galaxy sizes and fluxes, influencing the clustering patterns of galaxies through cosmic magnification. This effect enables the reconstruction of weak lensing co…
The direct measurement of gravitational potential decay rate at cosmological scales II -- Improved dark energy constraint from
Fuyu Dong, Pengjie Zhang, Haojie Xu +1
The gravitational potential decay rate (DR) is caused by the cosmic acceleration of the universe, providing a direct probe into the existence of dark energy (DE). We present measur…
