Constraining Dark Energy With Stacked Concave Lenses
Fuyu Dong, Jun Zhang, Yu Yu +6
Low density regions are less affected by the nonlinear structure formation and baryonic physics. They are ideal places for probing the nature of dark energy, a possible explanation…
Testing Shear Recovery with Field Distortion
Jun Zhang, Fuyu Dong, Hekun Li +7
The tilt, rotation, or offset of each CCD with respect to the focal plane, as well as the distortion of the focal plane itself, cause shape distortions to the observed objects, an…
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…
Testing the ABS method with the simulated Planck temperature maps
Jian Yao, Le Zhang, Yuxi Zhao +3
In this study, we apply the Analytical method of Blind Separation (ABS) of the cosmic microwave background (CMB) from foregrounds to estimate the CMB temperature power spectrum fro…
