Isotropic Radio Background from Quark Nugget Dark Matter
  Recent measurements by the ARCADE2 experiment unambiguously show an excess in
the isotropic radio background at frequencies below the GHz scale. We argue
that this excess may be a natural consequence of the interaction of visible and
dark matter in the early universe if the dark matter consists of heavy nuggets
of quark matter. Explanation of the observed radio band excess requires the
introduction of no new parameters, rather we exploit the same dark matter model
and identical normalization parameters to those previously used to explain
other excesses of diffuse emission from the centre of our galaxy. These
previously observed excesses include the WMAP Haze of GHz radiation, keV X -ray
emission and MeV gamma-ray radiation.
