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…
Multiwavelength monitoring of the enigmatic Narrow-Line Seyfert 1 PMN J0948+0022 in March-July 2009
LAT Collaboration, E. Angelakis, C. Bailyn +39
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 r…
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…
Constraining relativistic protons and magnetic fields in galaxy clusters through radio and gamma-ray observations : the case of A2256
G. Brunetti
Giant radio halos are the most relevant examples of diffuse synchrotron emission from galaxy clusters. A number of these sources have very steep spectrum, with spectral index $α\ge…
Fermi/LAT discovery of gamma-ray emission from a relativistic jet in the narrow-line quasar PMN J0948+0022
LAT Collaboration, A. A. Abdo, G. Ghisellini +3
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…
Fermi/LAT discovery of gamma-ray emission from the flat-spectrum radio quasar PKS 1454-354
LAT Collaboration, A. A. Abdo, P. G. Edwards +4
We report the discovery by the Large Area Telescope (LAT) onboard the Fermi Gamma-ray Space Telescope of high-energy gamma-ray (GeV) emission from the flat-spectrum radio quasar PK…
A Decade of SN1993J: Discovery of Wavelength Effects in the Expansion Rate
J. M. Marcaide, I. Marti-Vidal, A. Alberdi +15
We have studied the growth of the shell-like radio structure of supernova SN1993J in M81 from September 1993 through October 2003 with very-long-baseline interferometry (VLBI) obse…
Bright AGN Source List from the First Three Months of the Fermi Large Area Telescope All-Sky Survey
A. A. Abdo
The first three months of sky-survey operation with the Fermi Gamma Ray Space Telescope (Fermi) Large Area Telescope (LAT) reveals 132 bright sources at |b|>10 deg with test statis…
The Jet of 3C 17 and the Use of Jet Curvature as a Diagnostic of the X-ray Emission Process
F. Massaro, D. E. Harris, M. Chiaberge +5
We report on the X-ray emission from the radio jet of 3C 17 from Chandra observations and compare the X-ray emission with radio maps from the VLA archive and with the optical-IR ar…
Extended X-ray emission in radio galaxies: the peculiar case of 3C 305
F. Massaro, M. Chiaberge, P. Grandi +8
Extended X-ray structures are common in Active Galactic Nuclei (AGNs). Here we present the first case of a Compact Steep Spectrum (CSS) radio galaxy, 3C 305, in which the X-ray rad…
High energy emission from galaxy clusters and particle acceleration due to MHD turbulence
G. Brunetti, P. Blasi, R. Cassano +1
In the next years the FERMI gamma ray telescope and the Cherenkov telescopes will put very stringent constraints to models of gamma ray emission from galaxy clusters providing cruc…
