Real-space 1D matter power spectra
The real-space 1D matter 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. The solid line is the prediction using the formalism of
Peacock & Dodds (1996, MNRAS, 280, 19).
