Can Planck constrain indirect detection of dark matter in our galaxy?

Understand

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 of the dark matter plus astrophysical source synchrotron emission is frequency-dependent.
• We show that a thorough comparison between LFI and HFI data can potentially provide a new tool for constraining the dark matter particle mass.
