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

  2. 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 Vanessa Mangano - Venice 2006

  3. 1 High z/XRF 8 High z/GRB 3 Short 8 XRF 20 Others 26 GRB with flares 14 GRB w/o flares The sample Vanessa Mangano - Venice 2006

  4. The redshift distribution Vanessa Mangano - Venice 2006

  5. Previous works Chincarini et al. 2005 Nousek at al. 2006 Vanessa Mangano - Venice 2006

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

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

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

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

  10. X-ray luminosities at fixed rest frame times since the trigger @ 35 s @ 1 ks @ 11 hr Only the continuum underlying flares Vanessa Mangano - Venice 2006

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

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

  13. The durations of long bursts Vanessa Mangano - Venice 2006

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

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

  16. Energetics 15-150 keV rest frame energy of the prompt versus 0.2-10 keV rest frame energy of the afterglow X-rays from 35 to 1000 s X-rays from 1000 s to 11 hr Vanessa Mangano - Venice 2006

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