TeV gamma rays from the blazar H 1426+428 and the diffuse extragalactic background radiation
The detection of TeV γ-rays from the blazar H 1426+428 at an integral flux level of above 1 TeV with the HEGRA imaging atmospheric Cherenkov telescope system is reported. H 1426+428 is located at a redshift of 0.129, which makes it the most distant source detected in TeV γ-rays so …
