  • The Fermi blazar sequence The Fermi blazar sequence
    Ghisellini, G; Righi, C; Costamante, L ... Monthly notices of the Royal Astronomical Society, 07/2017, Letnik: 469, Številka: 1
    Journal Article
    Recenzirano
    Odprti dostop

    Abstract We revisit the blazar sequence exploiting the complete, flux-limited sample of blazars with known redshift detected by the Fermi satellite after 4 yr of operations (the 3LAC sample). We ...

  • Fermi/LAT broad emission li... Fermi/LAT broad emission line blazars
    Ghisellini, G; Tavecchio, F Monthly notices of the Royal Astronomical Society, 04/2015, Letnik: 448, Številka: 2
    Journal Article
    Recenzirano
    Odprti dostop

    We study the broad emission line blazars detected in the γ-ray band by the Large Area Telescope onboard the Fermi satellite and with the optical spectrum studied by Shaw et al. The observed broad ...

  • High-energy cosmic neutrino... High-energy cosmic neutrinos from spine-sheath BL Lac jets
    Tavecchio, F; Ghisellini, G Monthly notices of the Royal Astronomical Society, 08/2015, Letnik: 451, Številka: 2
    Journal Article
    Recenzirano
    Odprti dostop

    We recently proposed that structured (spine-sheath) jets associated with BL Lac objects could offer a suitable environment for the production of the extragalactic high-energy (E > 100 TeV) neutrino ...

  • Canonical high-power blazars Canonical high-power blazars
    Ghisellini, G.; Tavecchio, F. Monthly notices of the Royal Astronomical Society, August 2009, Letnik: 397, Številka: 2
    Journal Article
    Recenzirano
    Odprti dostop

    The jets of powerful blazars propagate within relatively dense regions of radiation produced externally to the jet. This radiation is a key ingredient to understand the origin of the high-energy ...

  • On-axis view of GRB 170817A On-axis view of GRB 170817A
    Salafia, O. S.; Ghirlanda, G.; Ascenzi, S. ... Astronomy and astrophysics (Berlin), 08/2019, Letnik: 628
    Journal Article
    Recenzirano
    Odprti dostop

    The peculiar short gamma-ray burst (SGRB) GRB 170817A has been firmly associated to the gravitational wave event GW170817, which has been unanimously interpreted as due to the coalescence of a double ...

  • Electron–positron pairs in ... Electron–positron pairs in blazar jets and γ‐ray loud radio galaxies
    Ghisellini, G. Monthly notices of the Royal Astronomical Society. Letters, July 2012, 2012-07-01, 20120701, Letnik: 424, Številka: 1
    Journal Article
    Recenzirano
    Odprti dostop

    ABSTRACT The matter content of extragalactic relativistic jets is still an unsolved issue. There are strong arguments against pure electron–positron pair jets, but pairs could outnumber the electrons ...

  • On the magnetization of BL ... On the magnetization of BL Lac jets
    Tavecchio, F; Ghisellini, G Monthly notices of the Royal Astronomical Society, 03/2016, Letnik: 456, Številka: 3
    Journal Article
    Recenzirano
    Odprti dostop

    The current paradigm foresees that relativistic jets are launched as magnetically dominated flows, whose magnetic power is progressively converted to kinetic power of the matter of the jet, until ...

  • The transition between BL L... The transition between BL Lac objects and flat spectrum radio quasars
    Ghisellini, G.; Tavecchio, F.; Foschini, L. ... Monthly notices of the Royal Astronomical Society, July 2011, Letnik: 414, Številka: 3
    Journal Article
    Recenzirano
    Odprti dostop

    We study the BL Lac objects detected in the 1-year all-sky survey of the Fermi satellite, with an energy spectral slope αγ in the 0.1-100 GeV band greater than 1.2. In the αγ versus γ-ray luminosity ...

  • The power of relativistic j... The power of relativistic jets is larger than the luminosity of their accretion disks
    Ghisellini, G; Tavecchio, F; Maraschi, L ... Nature (London), 2014-Nov-20, 2014-11-20, 20141120, Letnik: 515, Številka: 7527
    Journal Article
    Recenzirano
    Odprti dostop

    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 ...

  • The evolution of the X-ray ... The evolution of the X-ray afterglow emission of GW 170817/ GRB 170817A in XMM-Newton observations
    D’Avanzo, P.; Campana, S.; Salafia, O. S. ... Astronomy and astrophysics (Berlin), 05/2018, Letnik: 613
    Journal Article
    Recenzirano
    Odprti dostop

    We report our observation of the short gamma-ray burst (GRB) GRB 170817A, associated to the binary neutron star merger gravitational wave (GW) event GW 170817, performed in the X-ray band with ...
