Time-resolved spectral correlations of long-duration Gamma-Ray Bursts
C. Firmani, J. I. Cabrera, V. Avila-Reese +4
For a sample of long GRBs with known redshift, we study the distribution of the evolutionary tracks on the rest-frame luminosity-peak energy Liso-Ep' diagram. We are interested in…
Peak energy of the prompt emission of long Gamma Ray Bursts vs their fluence and peak flux
Lara Nava, Giancarlo Ghirlanda, Gabriele Ghisellini +1
The spectral-energy and (luminosity) correlations in long GRBs are being hotly debated to establish, first of all, their reality against possible selection effects. These are best…
Precursors in Swift Gamma Ray Bursts with redshift
D. Burlon, G. Ghirlanda, G. Ghisellini +4
We study a sample of Gamma-Ray Bursts detected by the Swift satellite with known redshift which show a precursor in the Swift-BAT light curve. We analyze the spectra of the precurs…
Comments on ``Are Swift Gamma-Ray Bursts consistent with the Ghirlanda relation?", by Campana et al.(astro--ph/0703676)
G. Ghirlanda, L. Nava, G. Ghisellini +1
In their recent paper, Campana et al. (2007) found that 5 bursts, among those detected by Swift, are outliers with respect to the E_peak-E_gamma ("Ghirlanda") correlation. We inste…
The role of afterglow break-times as GRB jet angle indicators
L. Nava, G. Ghisellini, G. Ghirlanda +3
The early X-ray light curve of Gamma Ray Bursts (GRBs) is complex, and shows a typical steep-flat-steep behaviour. The time T_a at which the flat (plateau) part ends may bear some…
"Late prompt" emission in Gamma Ray Bursts?
G. Ghisellini, G. Ghirlanda, L. Nava +1
The flat decay phase in the first 1e2-1e4 seconds of the X-ray light curve of Gamma Ray Bursts (GRBs) has not yet found a convincing explanation. The fact that the optical and X-ra…
