Probing Lorentz Invariance Violation with Absorption of Astrophysical γ-Rays by Solar Photons

The Astrophysical Journal
We compute in detail the absorption optical depth for astrophysical γ -ray photons interacting with solar photons to produce electron–positron pairs. This effect is greatest for γ -ray sources at small angular distances from the Sun, reaching optical ...
