Measurements of the anisotropy power spectrum of the cosmic near-infrared background radiation show the clustering amplitude to be larger than existing model predictions involving distant primordial galaxies or nearby faint galaxies: the fluctuations are proposed to originate from intrahalo stars of all galaxies with dark-matter haloes of 109 to 1012 solar masses at redshifts of about 1 to 4.
