The faster the narrower: characteristic bulk velocities and jet opening angles of Gamma Ray Bursts

G. Ghirlanda, G. Ghisellini, R. Salvaterra +6

The jet opening angle theta_jet and the bulk Lorentz factor Gamma_0 are crucial parameters for the computation of the energetics of Gamma Ray Bursts (GRBs). From the ~30 GRBs with…

A complete sample of bright Swift Gamma-Ray Bursts: X-ray afterglow luminosity and its correlation with the prompt emission

P. D'Avanzo, R. Salvaterra, B. Sbarufatti +12

We investigate wheter there is any correlation between the X-ray afterglow luminosity and the prompt emission properties of a carefully selected sub-sample of bright Swift long Gam…

The Optical SN 2012bz Associated with the Long GRB 120422A

A. Melandri, E. Pian, P. Ferrero +34

The association of Type Ic SNe with long-duration GRBs is well established. We endeavor, through accurate ground-based observational campaigns, to characterize these SNe at increas…

On the Environment of Short Gamma-ray Bursts

D. Kopač, P. D'Avanzo, A. Melandri +8

In this paper we present a sample of 10 short gamma-ray bursts (GRBs) with a robust redshift determination, discovered by the Swift satellite up to January 2011. We measure their X…

The impact of selection biases on the Ep-Liso correlation of Gamma Ray Bursts

G. Ghirlanda, G. Ghisellini, L. Nava +8

We study the possible effects of selection biases on the Ep-Liso correlation caused by the unavoidable presence of flux-limits in the existing samples of Gamma Ray Bursts (GRBs). W…
