Discovery of TeVγ-ray emission from PKS 0447-439 and derivation of an upper limit on its redshift
A. Abramowski, F. Acero, A. G. Akhperjanian, G. Anton et autres
Very high-energy γ-ray emission from PKS 0447−439 was detected with the H.E.S.S. Cherenkov telescope array in December 2009. This blazar is one of the brightest extragalactic objects in the Fermi bright source list and has a hard spectrum in the MeV to …
