AKARI near-infrared background fluctuations arise from normal galaxy
  populations
  We show that measurements of the fluctuations in the near-infrared background
(NIRB) from the AKARI satellite can be explained by faint galaxy populations at
low redshifts. We demonstrate this using reconstructed images from deep galaxy
catalogs (HUGS/S-CANDELS) and two independent galaxy population models. In all
cases, we find that the NIRB fluctuations measured by AKARI are consistent with
faint galaxies and there is no need for a contribution from unknown
populations. We find no evidence for a steep Rayleigh-Jeans spectrum for the
underlying sources as previously reported. The apparent Rayleigh-Jeans spectrum
at large angular scales is likely a consequence of galaxies being removed
systematically to deeper levels in the longer wavelength channels.
