TL;DR: Excess clustering over the linear prediction at arcminute angular scales in the power spectrum of brightness fluctuations at 250, 350 and 500 μm is reported, and it is found that submillimetre galaxies are located in dark matter haloes with a minimum mass, Mmin, which corresponds to the most efficient mass scale for star formation in the Universe.
