The Vavilov-Cherenkov radiation by relict photon gas
arXiv:1009.0594
Abstract
Based on the new quantum Vavilov-Cherenkov,s radiation(VCR) theory (PRL,2004),it is stated the possibility of threshold realization in the modern epoch of the novel VCR effect by the relict photon gas, when it is traversed by relativistic particles of the cosmic rays with γ\geq γ_th \cong 2 \cdot 10^10, where γ^2 = 1 - \frac{V^2}{C^2}, v is the speed of particles, and c is the speed of the light in vacuum.
