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…
On the baryonic, stellar, and luminous scaling relations of disk galaxies
V. Avila-Reese, J. Zavala, C. Firmani +1
We explore how the slopes and scatters of the scaling relations of disk galaxies (Vm-L[-M], R-L[-M], and Vm-R) do change when moving from B to K bands and to stellar and baryonic q…
Re-born fireballs in Gamma-Ray Bursts
G. Ghisellini, A. Celotti, G. Ghirlanda +2
We consider the interaction between a relativistic fireball and material assumed to be still located just outside the progenitor star. Only a small fraction of the expected mass is…
Black-body components in Gamma-Ray Bursts spectra?
G. Ghirlanda, Z. Bosnjak, G. Ghisellini +2
We study 7 Gamma Ray Bursts (GRBs), detected both by the BATSE instrument, on-board the Compton Gamma Ray Observatory, and by the Wide Field Camera (WFC), on-board BeppoSAX. These…
Spectral analysis of Swift long GRBs with known redshift
J. I. Cabrera, C. Firmani, V. Avila-Reese +3
We study the spectral and energetics properties of 47 long-duration gamma-ray bursts (GRBs) with known redshift, all of them detected by the Swift satellite. Due to the narrow ener…
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…
