Abstract :
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.
