Subdominant Dark Matter sterile neutrino resonant production in the light of PLANCK

Popa, L. A.; Tonoiu, D.

Few independent detections of a weak X-ray line at an energy of ~ 3.5 keV seen toward a number of astrophysical sites have been reported. If this signal will be confirmed to be the signature of decaying DM sterile neutrino with a mass of ~ 7.1 keV, then the cosmological observables should be consistent with its properties.
