1 Vanessa Mangano - Venice 2006 Rest frame light curves of Swift GRBs Vanessa Mangano, Giancarlo Cusumano, Valentina La Parola, Eleonora Troja, Teresa Mineo

2 Vanessa Mangano - Venice 2006 Outline of the Talk The sample of Gamma-ray burst with known redshift triggered by Swift Their light curves: shape and and average properties Energetics

3 Vanessa Mangano - Venice GRB with flares 14 GRB w/o flares 8 High z/GRB 3 Short 8 XRF 20 Others 1 High z/XRF The sample

4 Vanessa Mangano - Venice 2006 The redshift distribution

5 Vanessa Mangano - Venice 2006 Nousek at al Chincarini et al Previous works

6 Vanessa Mangano - Venice 2006 luminosity light curves with 4 < z < 7 =49.8 ± 0.6 =48.3 ± 0.8 =46.1 ± 0.6

7 Vanessa Mangano - Venice 2006 =49.6 ± 0.5 =48.3 ± 0.9 =46.7 ± 0.6 luminosity light curves with 2 < z < 4

8 Vanessa Mangano - Venice 2006 =50.19 ± 0.73 =47.7 ± 0.6 =46.1 ± 0.7 luminosity light curves with 1 < z < 2

9 Vanessa Mangano - Venice 2006 Long bursts Short bursts Luminosity light curves with z < 1 =45.0 ± 0.8 =46.0 ± 1.5

10 Vanessa Mangano - Venice 2006 X-ray luminosities at fixed rest frame times since the hr Only the continuum underlying flares

11 Vanessa Mangano - Venice 2006 Afterglow light curves with two breaks (at least) Light curves with one break no breaks...

12 Vanessa Mangano - Venice 2006 Average properties of the light curves

13 Vanessa Mangano - Venice 2006 The durations of long bursts

14 Vanessa Mangano - Venice 2006 Nousek et al Correlation between Eiso and the X-ray afterglow luminosity BeppoSAX and HETE data from Bloom et al Berger et al. 2003

15 Vanessa Mangano - Venice 2006 Using the larger Swift sample….. 10

16 Vanessa Mangano - Venice 2006 Energetics keV rest frame energy of the prompt versus keV rest frame energy of the afterglow X-rays from 35 to 1000 sX-rays from 1000 s to 11 hr

17 Vanessa Mangano - Venice 2006 To be continued…… Summary: Average properties of the luminosity light curves in rest frame studied in detail Energetics of flares and different afteglow phases need further investigation
