Over the past five years evidence has mounted that long-duration (>2 s) γ-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… 
No supernovae associated with two long-duration γ-ray bursts
It is now accepted that long-duration γ-ray bursts (GRBs) are produced during the collapse of a massive star1,2. The standard ‘collapsar’ model3 predicts that a broad-lined and luminous type Ic
Signatures of a jet cocoon in early spectra of a supernova associated with a γ-ray burst
Multi-epoch observations of a supernova associated with a γ-ray burst reveal spectral features at extremely high expansion velocities within the first day after the burst, indicative of a choked jet.
No supernovae detected in two long-duration gamma-ray bursts
It is found that the properties of the host galaxies, the long duration of the bursts and, in the case of GRB 060505, the location of the burst within its host, all imply a massive stellar origin.
A novel explosive process is required for the γ-ray burst GRB 060614
Over the past decade, our physical understanding of γ-ray bursts (GRBs) has progressed rapidly, thanks to the discovery and observation of their long-lived afterglow emission. Long-duration (≳2 s)
The ultra-long Gamma-Ray Burst 111209A: the collapse of a blue supergiant?
We present optical, X-ray and gamma-ray observations of GRB 111209A, at a redshift of z = 0.677. We show that this event was active in its prompt phase for about 25000 seconds, making it the longest
The Diversity of Gamma-Ray Burst Afterglows and the Surroundings of Massive Stars
The finding of a Type Ic supernova connected with GRB 030329 showed a massive star origin for this burst, supporting evidence for this association in previous bursts with light-curve bumps at the
A common origin for cosmic explosions inferred from calorimetry of GRB030329
Radio observations of GRB030329 indicate a common origin for cosmic explosions in which the energy in the highest-velocity ejecta is extremely variable, and the contribution of the γ-rays is energetically minor.
A very luminous magnetar-powered supernova associated with an ultra-long γ-ray burst
It is reported that a supernova was associated with the ultra-long-duration γ-ray burst GRB 111209A, at a redshift z of 0.677, and this supernova is more than three times more luminous than type Ic supernovae associated with long-duration μ-ray bursts, and its spectrum is distinctly different.
While there is mounting evidence that long gamma-ray bursts (GRBs) are associated with the collapse of massive stars, the detailed structure of their pre-supernova stage is still debatable.


The unusual afterglow of the γ-ray burst of 26 March 1998 as evidence for a supernova connection
Cosmic γ-ray bursts have now been firmly established as one of the most powerful phenomena in the Universe, releasing almost the rest-mass energy of a neutron star within the space of a few seconds
Radio emission from the unusual supernova 1998bw and its association with the γ-ray burst of 25 April 1998
Data accumulated over the past year strongly favour the idea that γ-ray bursts lie at cosmological distances, although the nature of the power source remains unclear. Here we report radio
A hypernova model for the supernova associated with the γ-ray burst of 25 April 1998
The discovery of the unusual supernova SN1998bw, and its possible association with the γ-ray burst GRB 980425, provide new insights into the explosion mechanism of very massive stars and the origin
The bright optical afterglow of the nearby γ-ray burst of 29 March 2003
Past studies of cosmological γ-ray bursts (GRBs) have been hampered by their extreme distances, resulting in faint afterglows. A nearby GRB could potentially shed much light on the origin of these
The signature of supernova ejecta in the X-ray afterglow of the γ-ray burst 011211
Now that γ-ray bursts (GRBs) have been determined to lie at cosmological distances, their isotropic burst energies are estimated to be as high as 1054 erg (ref. 2), making them the most energetic
An unusual supernova in the error box of the γ-ray burst of 25 April 1998
The discovery of afterglows associated with γ-ray bursts at X-ray, optical and radio wavelengths and the measurement of the redshifts of some of these events, has established that γ-ray bursts lie at
Gamma-Ray Bursts and Type Ic Supernova SN 1998bw
Recently a Type Ic supernova, SN 1998bw, was discovered coincident with a gamma-ray burst, GRB 980425. The supernova had unusual radio, optical, and spectroscopic properties. Among other things, it
Are Gamma-Ray Bursts in Star-Forming Regions?
The optical afterglow of the gamma-ray burst GRB 970508 (z=0.835) was a few hundred times more luminous than any supernova. Therefore, the name "hypernova" is proposed for the whole GRB/afterglow
Spectroscopic Discovery of the Supernova 2003dh Associated with GRB 030329
We present early observations of the afterglow of GRB 030329 and the spectroscopic discovery of its associated supernova SN 2003dh. We obtained spectra of the afterglow of GRB 030329 each night from
Hubble Space Telescope and Palomar imaging of GRB 990123: Implications for the nature of gamma-ray bursts and their hosts
We report on Hubble Space Telescope and Palomar optical images of the field of GRB 990123, obtained in 1999 February 8 and 9. We find that the optical transient (OT) associated with GRB 990123 is
