The new metagalactic source of gamma-quanta with energy $>1012 eV$

Observatory SHALON ALATOO has just announced the TeV discovered of NGC 1275. The TeV catalogue of extragalactic sources contains three objects investigated by the SHALON-ALATOO Observatory at energy above 0.8 TeV: Markarian 421, Markarian 501 and NGC 1275, which was detected in TeV energy range by the observation on the telescope SHALON-1. The flux appears to be about that of the Crab Nebula (the intensity of Active Galactic Nucleus NGC 1275 at energy above 0.8 TeV with the flux $(1.10±0.40)⋅10−12 cm−2s−1).$ Results obtained with the Mirror Cherenkov telescope SHALON-1 (mirror area more than 11 m²) point out that the Active Galactic Nuclei are main sources of gamma-quanta and probably cosmic rays of the high energy.
