The EMU view of the Large Magellanic Cloud: Troubles for sub-TeV WIMPs
  We present a radio search for WIMP dark matter in the Large Magellanic Cloud
(LMC). We make use of a recent deep image of the LMC obtained from observations
of the Australian Square Kilometre Array Pathfinder (ASKAP), and processed as
part of the Evolutionary Map of the Universe (EMU) survey. LMC is an extremely
promising target for WIMP searches at radio frequencies because of the large
J-factor and the presence of a substantial magnetic field. We detect no
evidence for emission arising from WIMP annihilations and derive stringent
bounds on the annihilation rate as a function of the WIMP mass, for different
annihilation channels. This work excludes the thermal cross section for masses
below 480 GeV and annihilation into quarks.
