Weak lensing power spectrum reconstruction by counting galaxies.-- II: Improving the ABS method with the shift parameter
Pengjie Zhang, Xinjuan Yang, Jun Zhang +1
In paper I of this series (Yang et al. 2017, ApJ), we proposed an analytical method of blind separation ({\bf ABS}) to extract the cosmic magnification signal in galaxy number dist…
Weak lensing power spectrum reconstruction by counting galaxies.-- I: the ABS method
Xinjuan Yang, Jun Zhang, Yu Yu +1
We propose an Analytical method of Blind Separation (ABS) of cosmic magnification from the intrinsic fluctuations of galaxy number density in the observed galaxy number density dis…
Weak lensing reconstruction through cosmic magnification. II. Improved power spectrum determination and map-making
Xinjuan Yang, Pengjie Zhang, Jun Zhang +1
The existence of galaxy intrinsic clustering severely hampers the weak lensing reconstruction from cosmic magnification. In paper I \citep{Yang2011}, we proposed a minimal variance…
Weak lensing reconstruction through cosmic magnification I: a minimal variance map reconstruction
Xinjuan Yang, Pengjie Zhang
We present a concept study on weak lensing map reconstruction through the cosmic magnification effect in galaxy number density distribution. We propose a minimal variance linear es…
