1. Observations of GRBs at high redshift.

    Philosophical Transactions of the Royal Society... 365(1854):1377 (2007) PMID 17293319

    The extreme luminosity of gamma-ray bursts and their afterglows means they are detectable, in principle, to very high redshifts. Although the redshift distribution of gamma-ray bursts (GRBs) is difficult to determine, due to incompleteness of present samples, we argue that for Swift-detected bur...

  3. No supernovae associated with two long-duration gamma-ray bursts.

    Nature 444(7122):1047 (2006) PMID 17183316

    It is now accepted that long-duration gamma-ray bursts (GRBs) are produced during the collapse of a massive star. The standard 'collapsar' model predicts that a broad-lined and luminous type Ic core-collapse supernova accompanies every long-duration GRB. This association has been confirmed in ob...

  5. The optical afterglow of the short gamma-ray burst GRB 050709.

    Nature 437(7060):859 (2005) PMID 16208365

    It has long been known that there are two classes of gamma-ray bursts (GRBs), mainly distinguished by their durations. The breakthrough in our understanding of long-duration GRBs (those lasting more than approximately 2 s), which ultimately linked them with energetic type Ic supernovae, came fro...

  7. Small-scale variations in the radiating surface of theGRB 011211jet

    New Astronomy 9(6):435 (2004)

    We report the discovery of the afterglow of the X-ray rich, long-duration γ-ray burst GRB 011211 and present evidence for oscillatory behaviour in its early optical light curve. The time-scale of the fluctuations, ∼1 h, is much smaller than the time of the observations, ∼12 h from th...

  9. A very energetic supernova associated with the gamma-ray burst of 29 March 2003.

    Nature 423(6942):847 (2003) PMID 12815425

    Over the past five years evidence has mounted that long-duration (>2 s) 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 supernov...
