Some DM candidates only show on through their couplings to photons, while evading more traditional search strategies such as Direct Detection, Indirect Detection or colliders. Using data from Planck mission we search for signals of interaction between the DM particles and CMB photons in local group DM dominated satellite galaxies and GCs. This research put direct constraints on the DM-photon cross section, for axions and axion-like DM particles.
