Radio signals of particle dark matter by Marco Regis

In most of particle dark matter (DM) models, the DM candidate injects sizable fluxes of high-energy electrons and positrons through its annihilations or decays. Emitted in regions with magnetic field, they in turn give raise to a synchrotron radiation, which typically covers radio and infrared bands. We discuss the possibility of detecting Galactic and extra-galactic DM signatures by looking at the induced synchrotron emission in DM halos.
