  • Fermi Discovery of Gamma-Ray Emission from NGC 1275
    Abdo, A.A.; Ackermann, M.; Ajello, M.; Asano, K.; Baldini, L.; Ballet, J.; Celotti, Annalisa (IOP Publishing, 2009-06-09)
    We report the discovery of high-energy (E>100 MeV) gamma-ray emission from NGC 1275, a giant elliptical galaxy lying at the center of the Perseus cluster of galaxies, based on observations made with the Large Area Telescope ...
  • Multiwavelength monitoring of the enigmatic Narrow-Line Seyfert 1 PMN J0948+0022 in March-July 2009
    Abdo, A.A.; Ackermann, M.; Ajello, M.; Axelsson, M.; Baldini, L.; Ballet, J.; Celotti, Annalisa (IOP Publishing, 2009-11-25)
    Following the recent discovery of gamma rays from the radio-loud narrow-line Seyfert 1 galaxy PMN J0948+0022 (z=0.5846), we started a multiwavelength campaign from radio to gamma rays, which was carried out between the end ...
