    • Afterglow calculation in the electromagnetic model for gamma-ray bursts 

      Genet, F.; Daigne, F.; Mochkovitch, R. (2006)
      We compute the afterglow of gamma-ray bursts produced by purely electromagnetic outflows to see if it shows characteristic signatures differing from those obtained with the standard internal/external shock model. Methods. ...

    • Can the early X-ray afterglow of gamma-ray bursts be explained by a contribution from the reverse shock 

      Genet, F.; Daigne, F.; Mochkovitch, R. (2007)

    • The circumstellar environment of Wolf-Rayet stars and gamma-ray burst afterglows 

      Eldridge, J.J.; Genet, F.; Daigne, F.; Mochkovitch, R. (2006)

    • GRB 081028 and its late-time afterglow re-brightening 

      Margutti, R.; Genet, F.; Granot, J.; Duran, R.B.; Guidorzi, C.; Chincarini, G.; Mao, J.; Schady, P.; Sakamoto, T.; Miller, A.A.; Olofsson, G.; Bloom, J.S.; Evans, P.A.; Fynbo, J.; Malesani, D.; Moretti, A.; Pasotti, F.; Starr, D.; Burrows, D.N.; Barthelmy, S.; Roming, P.W.A.; Gehrels, N. (2010)
      Swift captured for the first time a smoothly rising X-ray re-brightening of clear non-flaring origin after the steep decay in a long gamma-ray burst (GRB): GRB 081028. A rising phase is likely present in all GRBs but is ...

    • Is the Rapid Decay Phase from High Latitude Emission? 

      Genet, F.; Granot, J. (2009)
      There is good observationnal evidence that the Steep Decay Phase (SDP) that is observed in most Swift GRBs is the tail of the prompt emission. The most popular model to explain the SDP is Hight Latitude Emission (HLE). ...

    • Is the Rapid Decay Phase from High Latitude Emission? 

      Genet, F.; Granot, J. (American Institute of Physics (AIP), 2009)
      There is good observationnal evidence that the Steep Decay Phase (SDP) that is observed in most Swift GRBs is the tail of the prompt emission. The most popular model to explain the SDP is Hight Latitude Emission (HLE). ...

    • Late-time observations of GRB 080319B: jet break, host galaxy and accompanying supernova 

      Tanvir, N.; Rol, E.; Levan, A.; Svensson, K.; Fruchter, A.S.; Granot, J.; O'Brien, P.T.; Wiersema, K.; Starling, R.L.; Jakobsson, P.; Fynbo, J.; Hjorth, J.; Curran, P.; van der Horst, A.J.; Kouveliotou, C.; Racusin, J.L.; Burrows, D.N.; Genet, F. (2010)
      The Swift-discovered GRB 080319B was by far the most distant source ever observed at naked-eye brightness, reaching a peak apparent magnitude of 5.3 at a redshift of z = 0.937. We present our late-time optical (Hubble Space ...

    • The long rapid decay phase of the extended emission from the short GRB 080503 

      Genet, F.; Butler, N.R.; Granot, J. (2010)
      GRB 080503 was classified as a short gamma-ray burst (GRB) with extended emission. The origin of such extended emission (found in about a quarter of Swift short GRBs) is still unclear and may provide some clues to the ...

    • Realistic analytic model for the prompt and high-latitude emission in GRBs 

      Genet, F.; Granot, J. (2009)
      Most gamma-ray bursts (GRBs) observed by the Swift satellite show an early steep decay phase (SDP) in their X-ray light curve, which is usually a smooth continuation of the prompt gamma-ray emission, strongly suggesting ...

    • Rise and fall of the X-ray flash 080330: an off-axis jet? 

      Guidorzi, C.; Clemens, C.; Kobayashi, S.; Granot, J.; Melandri, A.; D'Avanzo, P.; Kuin, N.P.M.; Klotz, A.; Fynbo, J.; Covino, S.; Greiner, J.; Malesani, D.; Mao, J.; Mundell, C.G.; Steele, I.A.; Jakobsson, P.; Margutti, R.; Bersier, D.; Campana, S.; Chincarini, G.; D'Elia, V.; Fugazza, D.; Genet, F.; Gomboc, A.; Kruhler, T.; Yoldas, A.K.; Moretti, A.; Mottram, C.J.; O'Brien, P.T.; Smith, R.J.; Szokoly, G.; Tagliaferri, G.; Tanvir, N.; Gehrels, N. (2009)
      Context. X-ray flashes (XRFs) are a class of gamma-ray bursts (GRBs) with a peak energy of the time-integrated spectrum, , typically below 30 keV, whereas classical GRBs have of a few hundreds of keV. Apart from and the ...

    • The rise of the afterglow in GRB 050820a 

      Genet, F.; Daigne, F.; Mochkovitch, R. (2007)

    • The spectral–temporal properties of the prompt pulses and rapid decay phase of gamma-ray bursts 

      Willingale, R.; Genet, F.; Granot, J.; O'Brien, P.T. (2010)
      The prompt emission from gamma-ray burst is the brightest electromagnetic emission known, yet its origin is not understood. The flux density of individual prompt pulses of a GRB can be represented by an analytical expression ...
