Impact of uncertainties on the cosmic optical and infrared backgrounds on the propagation of astroparticles
Lucas Gréaux, Antonio Condorelli, Leonel Morejon +2
When propagating through the universe, gamma rays at very-high energy (VHE, E > 100 GeV) and ultra-high energy cosmic rays (UHECRs, E > 1 EeV) can interact with the optical, infrar…
