A unifying view of the spectral energy distributions of blazars
- G. Fossati, L. Maraschi, +7 authors Italy.
- Physics
- 9 April 1998
ABSTRA C T We collect data at well-sampled frequencies from the radio to the g-ray range for the following three complete samples of blazars: the Slew survey, the 1-Jy samples of BL Lacs and the 2-Jy… Expand
A theoretical unifying scheme for gamma-ray bright blazars
- G. Ghisellini, A. Celotti, G. Fossati, L. Maraschi, A. Comastri
- Physics
- 30 July 1998
ABSTRA C T The phenomenology of g-ray bright blazars can be accounted for by a sequence in the source power and intensity of the diffuse radiation field surrounding the relativistic jet.… Expand
The power of relativistic jets is larger than the luminosity of their accretion disks
- G. Ghisellini, F. Tavecchio, L. Maraschi, A. Celotti, T. Sbarrato
- Physics, Medicine
- Nature
- 19 November 2014
Theoretical models for the production of relativistic jets from active galactic nuclei predict that jet power arises from the spin and mass of the central supermassive black hole, as well as from the… Expand
Relativistic bulk motion in active galactic nuclei
- G. Ghisellini, P. Padovani, A. Celotti, L. Maraschi
- Physics
- 1 April 1993
We discuss the evidence for relativistic bulk motion of the emitting plasma in the nuclei of ∼100 radio sources, which include BL Lacertae objects, radio quasars, and radio galaxies, with published… Expand
The power of blazar jets
- A. Celotti, G. Ghisellini
- Physics
- 26 November 2007
We estimate the power of relativistic, extragalactic jets by modelling the spectral energy distribution of a large number of blazars. We adopt a simple one-zone, homogeneous, leptonic synchrotron and… Expand
FERMI LARGE AREA TELESCOPE OBSERVATIONS OF MISALIGNED ACTIVE GALACTIC NUCLEI
- A. Abdo, M. Ackermann, +172 authors M. Ziegler
- Physics
- 1 September 2010
Analysis is presented on 15 months of data taken with the Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope for 11 non-blazar AGNs, including 7 FRI radio galaxies and 4 FRII radio… Expand
GeV emission from gamma‐ray bursts: a radiative fireball?
- G. Ghisellini, G. Ghirlanda, L. Nava, A. Celotti
- Physics
- 13 October 2009
We study the emission observed at energies > 100 MeV of 11 gamma-ray bursts (GRBs) detected by the Fermi-Large Area Telescope (LAT) until 2009 October. The GeV emission has three main properties: (i)… Expand
Fermi Observations of High-Energy Gamma-Ray Emission from GRB 080916C
- A. Abdo, M. Ackermann, +249 authors M. Ziegler
- Physics, Medicine
- Science
- 27 March 2009
Gamma-ray bursts (GRBs) are highly energetic explosions signaling the death of massive stars in distant galaxies. The Gamma-ray Burst Monitor and Large Area Telescope onboard the Fermi Observatory… Expand
Jets and accretion processes in active galactic nuclei: further clues
- A. Celotti, P. Padovani, Gabriele Ghisellini Sissa, Italy., II Univ. Roma, Osserv. Astron. di Brera-Merate
- Physics
- 14 November 1996
We present evidence in favour of a link between the luminosity radiatively dissipated in the central engine of radio-loud Active Galactic Nuclei and the kinetic power in their jets. This piece of… Expand
A transition in the accretion properties of radio-loud active nuclei
- D. Marchesini, A. Celotti, L. F. S. -. Trieste, R. University
- Physics
- 11 March 2004
We present evidence for the presence of a transition in the accretion properties of radio-loud sources. For a sample of radio galaxies and radio-loud quasars, selected based on their extended radio… Expand
