Is the Radial Profile of the Phase-Space Density of Dark Matter Halos a Power-Law?
Chung-Pei Ma, Philip Chang, Jun Zhang
The latest cosmological N-body simulations find two intriguing properties for dark matter haloes: (1) their radial density profile, rho, is better fit by a form that flattens to a…

Measuring the Cosmic Shear in Fourier Space
Jun Zhang
We propose to measure the weak cosmic shear using the spatial derivatives of the galaxy surface brightness field. The measurement should be carried out in Fourier space, in which t…
