  It has been recently claimed that radio observations of nearby spiral
galaxies essentially rule out a dark matter source for the galactic haze. Here
we consider the low energy thermal emission from a quark nugget dark matter
model in the context of microwave emission from the galactic centre and radio
observations of nearby Milky Way like galaxies. We demonstrate that observed
emission levels do not strongly constrain this specific dark matter candidate
across a broad range of the allowed parameter space in drastic contrast with
conventional dark matter models based on the WIMP paradigm.
