Description
The recent detection of the gamma-ray burst GRB 221009A has garnered significant attention due to its unprecedented brightness and the first-ever detection of very-high energy (VHE, > 10 TeV) gamma rays from a GRB at the redshift of z=0.151. This redshift indicates a distance at which the gamma-ray flux at these energies would typically undergo severe attenuation due to gamma-gamma pair production with the extragalactic background light (EBL). In my talk, I will explore the possibility that cosmic voids along our line-of-sight to the source might significantly influence the detestability of such VHE gamma-ray photons.
