Ultra-High Energy Cosmic Rays and Diffuse Photon Spectrum

Tinyakov, P. G.

Original · EN

It is argued that if extragalactic magnetic fields are smaller than 2x10⁻¹² G the flux of ultra-high energy photons of (a few)x10⁻¹ eV cm⁻²s⁻¹sr⁻¹ predicted in the top-down models of UHE CR implies similar flux of the diffuse photons in the energy range 10¹⁵-10¹⁷ eV, which is close to the existing experimental limit.
