Energetic axion-like particle production in galaxies
arXiv:1104.1572
Abstract
Relativistic axion-like particles (ALPs) originating from the stellar interiors, along with the ones coming from photon-ALP mixing in the galactic magnetic fields, contribute together to make an energetic component of the ALP content of the universe. Considering an isotropic distribution of cosmic gamma rays, it is examined if these high energy axion-like particles could constitute a measurable isotropic "background" for helioscope-type and existing large general-purpose particle experiments, taking into account their sensitivity.
