Abstract
The extragalactic background light at far-infrared wavelengths1, 2, 3 comes from optically faint, dusty, star-forming galaxies in the Universe with star formation rates of a few hundred solar masses per year4. These faint, submillimetre galaxies are challenging to study individually because of the relatively poor spatial resolution of far-infrared telescopes5, 6. Instead, their average properties can be studied using statistics such as the angular power spectrum of the background intensity variations7, 8, 9, 10. A previous attempt11 at measuring this power spectrum resulted in the suggestion that the clustering amplitude is below the level computed with a simple ansatz based on a halo model12. Here we report excess clustering over the linear prediction at arcminute angular scales in the power spectrum of brightness fluctuations at 250, 350 and 500â\ensuremath\mu
