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…
A unifying view of Gamma Ray Burst Afterglows
G. Ghisellini, M. Nardini, G. Ghirlanda +1
We selected a sample of 33 Gamma Ray Bursts (GRBs) detected by Swift, with known redshift and optical extinction at the host frame. For these, we constructed the de-absorbed and K-…
TeV variability in blazars: how fast can it be?
G. Ghisellini, F. Tavecchio, G. Bodo +1
Recent Cerenkov observations of the two BL Lac objects PKS 2155-304 and Mkn 501 revealed TeV flux variability by a factor ~2 in just 3-5 minutes. Even accounting for the effects of…
Long lived central engines in Gamma Ray Bursts
G. Ghisellini
The central engine of Gamma Ray Bursts may live much longer than the duration of the prompt emission. Some evidence of it comes from the presence of strong precursors, post-cursors…
Structured jets and VHE emission of blazars and radiogalaxies
F. Tavecchio, G. Ghisellini
Recent observations in the TeV band challenge the simplest models developed to describe the overall emission of blazars and radiogalaxies. In particular, the observation of variabl…
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…
