  We present a deep radio search in the Reticulum II dwarf spheroidal (dSph)
galaxy performed with the Australia Telescope Compact Array. Observations were
conducted at 16 cm wavelength, with an rms sensitivity of 0.01 mJy/beam, and
with the goal of searching for synchrotron emission induced by annihilation or
decay of weakly interacting massive particles (WIMPs). Data were complemented
with observations on large angular scales taken with the KAT-7 telescope. We
find no evidence for a diffuse emission from the dSph and we derive competitive
bounds on the WIMP properties. In addition, we detect more than 200 new
background radio sources. Among them, we show there are two compelling
candidates for being the radio counterpart of the possible gamma-ray emission
reported by other groups using Fermi-LAT data.
