Convergence of 1D flux power spectra
The 1D flux power spectrum at z = 5 in a concordance
cosmology for a resolution sequence in Np/Ng, where Np = number of
particles and Ng = number of grid cells for a Particle-Mesh (PM)
simulation. (Upper panel) The density and velocity fields are smoothed
on the Jeans length scale using a gaussian filter. (Lower panel) The density
and velocity fields are smoothed on the Jeans length scale using a quadratic
filter. (From Meiksin & White 2004, MNRAS, 350, 1107.)
