Radio-Loud Narrow-Line Seyfert 1 as a New Class of Gamma-Ray AGN
LAT Collaboration, G. Ghisellini, L. Maraschi +1
We report the discovery with Fermi/LAT of gamma-ray emission from three radio-loud narrow-line Seyfert 1 galaxies: PKS 1502+036 (z=0.409), 1H 0323+342 (z=0.061) and PKS 2004-447 (z…
Fermi Large Area Telescope Gamma-Ray Detection of the Radio Galaxy M87
The Fermi LAT Collaboration, A. A. Abdo, D. E. Harris +2
We report the Fermi-LAT discovery of high-energy (MeV/GeV) gamma-ray emission positionally consistent with the center of the radio galaxy M87, at a source significance of over 10 s…
Variability Timescales in the M87 Jet: Signatures of E-Squared Losses, Discovery of a Quasi-period in HST-1, and the Site of TeV Flaring
D. E. Harris, C. C. Cheung, Lukasz Stawarz +2
We investigate the variability timescales in the jet of M87 with two goals. The first is to use the rise times and decay times in the radio, ultraviolet and X-ray lightcurves of HS…
The On-orbit Calibrations for the Fermi Large Area Telescope
The Fermi LAT Collaboration
The Large Area Telescope (LAT) on--board the Fermi Gamma ray Space Telescope began its on--orbit operations on June 23, 2008. Calibrations, defined in a generic sense, correspond t…
