On radiative acceleration in spine-sheath structured blazar jets
Atul Chhotray, Francesco Nappo, Gabriele Ghisellini +3
It has been proposed that blazar jets are structured, with a fast spine surrounded by a slower sheath or layer. This structured jet model explains some properties of their emission…
Structure of Gamma-Ray Burst jets: intrinsic versus apparent properties
O. S. Salafia, G. Ghisellini, A. Pescalli +2
With this paper we introduce the concept of apparent structure of a GRB jet, as opposed to its intrinsic structure. The latter is customarily defined specifying the functions epsil…
Luminosity function and jet structure of Gamma Ray Bursts
A. Pescalli, G. Ghirlanda, O. S. Salafia +3
The structure of Gamma Ray Burst (GRB) jets impacts on their prompt and afterglow emission properties. The jet of GRBs could be uniform, with constant energy per unit solid angle w…
Afterglows from precursors in Gamma Ray Bursts. Application to the optical afterglow of GRB 091024
F. Nappo, G. Ghisellini, G. Ghirlanda +3
About 15% of Gamma Ray Bursts have precursors, i.e. emission episodes preceding the main event, whose spectral and temporal properties are similar to the main emission. We propose…
