Discovery of very high energy gamma rays from PKS 1424+240 and multiwavelength constraints on its redshift
The VERITAS Collaboration, V. A. Acciari, The Fermi Collaboration +4
We report the first detection of very-high-energy (VHE) gamma-ray emission above 140 GeV from PKS 1424+240, a BL Lac object with an unknown redshift. The photon spectrum above 140…

Fermi/LAT discovery of gamma-ray emission from a relativistic jet in the narrow-line Seyfert 1 quasar PMN J0948+0022
L. Foschini, G. Ghisellini, L. Maraschi +2
We report the discovery by the Large Area Telescope (LAT) onboard the Fermi Gamma-ray Space Telescope of high-energy gamma-ray emission from the peculiar quasar PMN J0948+0022 (z=0…
