  • Vengono riportate le osservazioni eseguite col VLT dell'afterglow ottico del Gamma-Ray Burst GRB030329. La spettroscopia mette in evidenza l'esistenza e l'evoluzione di uno spettro di SN sovraspposto al continuo spettrale dell'afterglow. Questa e' una chiara conferma dell'associazione tra almeno alcuni Gamma-Ray Burst e SN. L'impatto di queste misure e' fondamentale per la comprensione del fenomeno GRB e della natura dei progenitori.

Abstract
  • Over the past five years evidence has mounted that long-duration (> 2s) gamma-ray bursts (GRBs)-the most luminous of all astronomical explosions-signal the collapse of massive stars in our Universe. This evidence was originally based on the probable association of one unusual GRB with a supernova, but now includes the association of GRBs with regions of massive star formation in distant galaxies, the appearance of supernova-like 'bumps' in the optical afterglow light curves of several bursts and lines of freshly synthesized elements in the spectra of a few X-ray afterglows. These observations support, but do not yet conclusively demonstrate, the idea that long-duration GRBs are associated with the deaths of massive stars, presumably arising from core collapse. Here we report evidence that a very energetic supernova (a hypernova) was temporally and spatially coincident with a GRB at redshift z = 0.1685. The timing of the supernova indicates that it exploded within a few days of the GRB, strongly suggesting that core-collapse events can give rise to GRBs, thereby favouring the 'collapsar' model.
