Long γ-ray bursts and core-collapse supernovae have different environments

- Nature
- 20 March 2006
When massive stars exhaust their fuel, they collapse and often produce the extraordinarily bright explosions known as core-collapse supernovae. On occasion, this stellar collapse also powers an even… Expand
A hypernova model for the supernova associated with the γ-ray burst of 25 April 1998
- K. Iwamoto, P. A. Mazzali, +24 authors F. Frontera
- Physics
- Nature
- 30 June 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… Expand
A very energetic supernova associated with the γ-ray burst of 29 March 2003
- J. Hjorth, J. Sollerman, +24 authors R. Wijers
- Physics
- Nature
- 17 June 2003
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… Expand
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… Expand

An optical supernova associated with the X-ray flash XRF 060218
- E. Pian, P. Mazzali, +42 authors R. Starling
- Physics, Medicine
- Nature
- 20 March 2006
Long-duration γ-ray bursts (GRBs) are associated with type Ic supernovae that are more luminous than average and that eject material at very high velocities. Less-luminous supernovae were not… Expand
Low-resolution Spectroscopy of Gamma-ray Burst Optical Afterglows: Biases in the Swift Sample and Characterization of the Absorbers
- J. Fynbo, Páll Jakobsson, +39 authors P.-O. Quirion
- Physics
- 20 July 2009
We present a sample of 77 optical afterglows (OAs) of Swift detected gamma-ray bursts (GRBs) for which spectroscopic follow-up observations have been secured. Our first objective is to measure the… Expand
The Metamorphosis of SN 1998bw
- F. Patat, E. Cappellaro, +23 authors E. Pian
- Physics
- 7 March 2001
We present and discuss the photometric and spectroscopic evolution of the peculiar SN 1998bw, associated with GRB 980425, through an analysis of optical and near-IR data collected at ESOLa Silla. The… Expand
IFU observations of the GRB 980425/SN 1998bw host galaxy : emission line ratios in GRB regions
- L. Christensen, P. Vreeswijk, J. Sollerman, C. C. Thöne, E. Floc’h, K. Wiersema
- Physics
- 22 July 2008
Context. The collapsar model predicts that the progenitors of Gamma-ray Bursts (GRBs) are metal poor in Fe group elements. The existence of low metallicity stellar populations could manifest itself… Expand
