Abstract

We report on a multiwavelength campaign for the radio-loud narrow-line Seyfert 1 (NLS1) galaxy PMNJ0948+0022 (z= 0.5846) performed in 2010 July-September and triggered by a high-energy γ-ray outburst observed by the Large Area Telescope onboard the Fermi Gamma-ray Space Telescope. The peak flux in the 0.1-100 GeV energy band exceeded, for the first time in this type of source, the value of ~10^-6 photon cm^-2s^-1, corresponding to an observed luminosity of ~10⁴⁸ergs^-1. Although the source was too close to the Sun position to organize a densely sampled follow-up, it was possible to gather some multiwavelength data that confirmed the state of high activity across the sampled electromagnetic spectrum. The comparison of the spectral energy distribution of the NLS1 PMNJ0948+0022 with that of a typical blazar - such as 3C273 - shows that the power emitted at γ-rays is extreme.
