Distant metagalactic sources of very high energy γ rays: 1739 + 522 and 3c454.3

Sources with red shifts from z = 0.0179 to 1.375 have been observed with the SHALON telescope. Fluxes, spectral energy distributions, integrated spectra, and images of new (in the TeV energy range) distant sources—flat-spectrum radio quasars 1739 + 522 and 3c454.3—are reported. It is shown that the...

Description
Summary:Sources with red shifts from z = 0.0179 to 1.375 have been observed with the SHALON telescope. Fluxes, spectral energy distributions, integrated spectra, and images of new (in the TeV energy range) distant sources—flat-spectrum radio quasars 1739 + 522 and 3c454.3—are reported. It is shown that the energy spectrum of metagalactic sources (Mkn421 and Mkn501 quasars) in the energy range 10 12 –10 13 eV in the power-law representation differs from the spectrum of 1739 + 522 and 3c454.4 distant quasars, which do not contradict the unified energy spectrum F (> E ) ∼ E γ −1.26±0.15 .
