The effects of EBL inhomogeneity on the gamma-gamma absorption of VHE gamma-rays
Abdalla, Hassan; Böttcher, Markus (HEASA, 2016)Very High Energy Gamma Rays (VHE; more than 100 GeV) from Cosmological Gamma Ray Sources such as blazars can be absorbed by the Extragalactic Background light (EBL), which leads to a high-energy cut-off in blazar spectral ... -
Lorentz invariance violation effects on gamma-gamma absorption and compton scattering
Abdalla, Hassan; Böttcher, Markus (IOP Publishing, 2018)In this paper, we consider the impact of the Lorentz invariance violation (LIV) on the γ − γ opacity of the universe to very high energy (VHE) gamma-rays, compared to the effect of local underdensities (voids) of the ...
