2014/12/24
We analyse the flux power spectrum and its covariance using simulated Lyα forests. We find that pseudo-hydro techniques are good approximations of hydrodynamical simulations at high redshift. However,...
The galaxy angular correlation functions and power spectrum from the Two Micron All Sky Survey
general statistics
