On the relation between dynamics and geometry in GRBs
G. Ghirlanda, S. Campana, S. Covino +7
We estimate the initial bulk Lorentz factors Gamma_0 for GRBs that show the onset of the afterglow in their optical light curves. We find that Gamma_0 is strongly correlated with b…
Radio afterglows of a complete sample of bright Swift GRBs: predictions from present days to the SKA era
G. Ghirlanda, R. Salvaterra, D. Burlon +13
Radio observations of Gamma Ray Bursts afterglows are fundamental in providing insights into their physics and environment, and in constraining the true energetics of these sources…
How to switch on and off a Gamma-ray burst through a magnetar
M. G. Bernardini, S. Campana, G. Ghisellini +11
One of the most elusive features of Gamma Ray Bursts (GRBs) is the sporadic emission prior to the main prompt event observed in at least of cases. These precursors have…
The AT20G view of Swift/BAT selected AGN: high-frequency radio waves meet hard X-rays
D. Burlon, G. Ghirlanda, T. Murphy +3
We cross-matched the 6-year Swift/Burst Alert Telescope (BAT) survey of active galactic nuclei (AGN) with the AT20G radio survey of the southern sky, which is one of the largest hi…
