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…

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…

On Measuring the 21 cm Global Spectrum of the Cosmic Dawn with an Interferometer Array
Xin Zhang, Bin Yue, Yuan Shi +2
We theoretically investigate the recovery of global spectrum (monopole) from visibilities (cross-correlation only) measured by the interferometer array and the feasibility of extra…
