Radio constraints on Galactic WIMP dark matter
  Synchrotron emission from electron cosmic ray populations can be used to
study both cosmic rays physics and WIMP dark matter imprints on radio skymaps.
We used available radio data - from MHz to GHz - to analyze the contribution
from galactic WIMP annihilations and impose constraints on WIMP observables:
annihilation cross section, channel and mass. Depending on the annihilation
channel we obtain as competitive bounds as those obtained in FERMI-LAT gamma
ray analysis of dwarf satellite galaxies.
