GRB 090423 at a redshift of z ≈ 8.1
Gamma-ray bursts (GRBs) are produced by rare types of massive stellar explosion. Their rapidly fading afterglows are often bright enough at optical wavelengths that they are detectable atExpand

An unusual supernova in the error box of the γ-ray burst of 25 April 1998
TLDR
We report the discovery of transient optical emission in the error box of the γ-ray burst GRB980425, the light curve of which was very different from that of previous optical afterglows associated with β�-ray bursts. Expand

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

Supernova SN 2011fe from an exploding carbon–oxygen white dwarf star
Type Ia supernovae have been used empirically as ‘standard candles’ to demonstrate the acceleration of the expansion of the Universe even though fundamental details, such as the nature of theirExpand

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 originExpand

A very energetic supernova associated with the γ-ray burst of 29 March 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. ThisExpand

An optical supernova associated with the X-ray flash XRF 060218
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 notExpand

A neutron-star-driven X-ray flash associated with supernova SN 2006aj
Supernovae connected with long-duration γ-ray bursts (GRBs) are hyper-energetic explosions resulting from the collapse of very massive stars (∼40 M[circdot], where M[circdot] is the mass of the Sun)Expand

Spectroscopic identification of r-process nucleosynthesis in a double neutron-star merger
The merger of two neutron stars is predicted to give rise to three major detectable phenomena: a short burst of γ-rays, a gravitational-wave signal, and a transient optical–near-infrared sourceExpand

Bolometric light curves and explosion parameters of 38 stripped-envelope core-collapse supernovae
Literature data are collated for 38 stripped-envelope core-collapse supernovae (SE SNe; i.e. SNe IIb, Ib, Ic and Ic-BL) that have good light curve coverage in more than one optical band. UsingExpand
