Weak Lensing Reconstruction by Counting Galaxies: Improvement with DES Y3 Galaxies
Jian Qin, Pengjie Zhang, Yu Yu +4
In \citep{Qin+}, we attempted to reconstruct the weak lensing convergence map from cosmic magnification by linearly weighting the DECaLS galaxy overdensities in different m…

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…
