Particle Production in the Interstellar Medium
G. Ingelman, M. Thunman
Abstract
The flux of neutrinos and photons originating from cosmic ray interactions with the interstellar medium in the galaxy is calculated based on current models for high energy particle interactions. The contribution from a possible dark matter halo of the galaxy is considered. The photon flux gets a non-trivial attenuation due to interactions with the cosmic background radiation. The neutrino fluxes are compared with those originating from the Earth's atmosphere as well as from active galactic nuclei.
