Constraints on dark matter annihilation in the Large Magellanic Cloud from multiple low-frequency radio observations

Zhanfang Chen, Feng Huang, Taotao Fang

Low-frequency radio emission from the Large Magellanic Cloud~(LMC) is assumed to be dominated by nonthermal synchrotron radiation from energy loss of energetic $e^{+}/e^{-}$ in magneti…
