ABSTRACT

We investigate the synchrotron emission (both intensity and morphology) associated with generic dark matter particles and make predictions for the Planck experiment, using the Fermi data and a model for the astrophysical sources. Our results indicate that the morphology (and not only the intensity) of the synchrotron emission from both dark matter annihilations plus astrophysical source is frequency dependent. Expected signals for light and heavy dark matter candidates seem sufficiently different to potentially delineate the value of the dark matter mass using a thorough comparison between LFI and HFI data.
