Cosmic Velocity Field Reconstruction Using AI
Ziyong Wu, Zhenyu Zhang, Shuyang Pan +6
We develop a deep learning technique to infer the non-linear velocity field from the dark matter density field. The deep learning architecture we use is an "U-net" style convolutio…

Cosmological constraints from the redshift dependence of the Alcock-Paczynski effect: Fourier space analysis
Xiaolin Luo, Ziyong Wu, Xiao-Dong Li +3
The tomographic Alcock-Paczynski (AP) method utilizes the redshift evolution of the AP distortion to place constraints on cosmological parameters. It has proved to be a robust meth…
