The new distant metagalactic γ-sources 1739+522 ( z = 1.375) and 3c454.3 ( z = 0.857) are detected at energies E > 0.8 TeV with the fluxes (0.53 ± 0.10) × 10-12 cm -2 s -1 and (0.43 ± 0.13) × 10-12 cm -2 s -1, respectively. The γ-ray spectra and fluxes of known blazars Mkn 421, Mkn 501 and distant flat-spectrum radio quasars 1739+522 and 3c454.3 are presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
