Issue Date: | 2021 | Journal: | JOURNAL OF COSMOLOGY AND ASTROPARTICLE PHYSICS | Number: | 2021 | Issue: | 11 | First Page: | 046 | Abstract: | 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. | URI: | http://hdl.handle.net/20.500.12386/32270 | URL: | https://iopscience.iop.org/article/10.1088/1475-7516/2021/11/046 https://arxiv.org/abs/2106.08025 |
