We report a search for fluctuations of the sky brightness toward the north ecliptic pole with the Japanese infrared astronomical satellite AKARI, at 2.4, 3.2, and 4.1 {mu}m. We obtained circular maps with 10' diameter fields of view, which clearly show a spatial structure on the scale of a few hundred arcseconds. A power spectrum analysis shows that there is a significant excess fluctuation at angular scales larger than 100'' that cannot be explained by zodiacal light, diffuse Galactic light… Expand

Near-infrared background anisotropies from diffuse intrahalo light of galaxies
A measurement of the anisotropy power spectrum from subarcminute to one-degree angular scales is reported, and it is found that the measured power spectrum can be explained by an intrahalo light fraction relative to the total luminosity in dark-matter haloes at redshifts of about 1 to 4.2 per cent.
