Circular polarization of cosmic photons due to their interactions with sterile neutrino dark matter


Abstract: Astrophysical searches of Warm Dark Matter (WDM) candidate in new physics are essential part of the experimental efforts to explore the nature of WDM. In this talk, I will propose an indirect method to search for WDM particles via studying their effects on the polarization of cosmic photons through cosmic photon-sterile neutrino scattering. I will consider GRB photons, galactic and extra galactic radio photons and the CMB photons as sources of cosmic rays and I will report the amount of possible circular polarization for each case via their scattering from the Sterile neutrino. This method might open a new observational window to ex ...
