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 analyses.
