Correlative Analysis of GRBs detected by Swift, Konus and HETE.

Swift has now detected a large enough sample of gamma-ray bursts (GRBs) to allow correlation studies of burst parameters. Such studies of earlier data sets have yielded important results leading to further understanding of burst parameters and classifications. This work focusses on seventeen Swift bursts that have also been detected either by Konus-Wind or HETE-II, providing high energy spectra and fits to Epeak . Eight of these bursts have spectroscopic redshifts and for others we can estimate redshifts using the variability/luminosity relationship. We can also compare Epeak with Eiso, and for those bursts for which a jet break was observed in the afterglow we can derive Eg and test the relationship between Epeak and Eγ . For all bursts we can derive durations and hardness ratios from the prompt emission. © 2006 American Institute of Physics [ABSTRACT FROM AUTHOR]
