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-ray1, optical2 and radio3 wavelengths and the measurement of the redshifts of some of these events4,5 has established that γ-ray bursts lie at extreme...

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 9804251,2,3, provide new insights into the explosion mechanism of very massive stars and the origin of some c...

The effect of magnetic fields on γ-ray bursts inferred from multi-wavelength observations of the burst of 23 January 1999
Gamma-ray bursts (GRBs) are thought to arise when an extremely relativistic outflow of particles from a massive explosion (the nature of which is still unclear) interacts with material surrounding the site of ...

Gamma-Ray Burst Afterglows as Probes of High-Z Star Formation
Gamma-Ray Bursts (GRBs) are bright and distant explosions, caused by the death of a massive star, making them excellent probes of star formation at all redshifts. One application of GRBs is to perform optical ...

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 even more brill...

An optical supernova associated with the X-ray flash XRF 060218
A link between long γ-ray bursts (GRBs) and supernovae has been established, but whether there is a similar relationship between the weaker and softer X-ray flashes and supernovae is unclear. GRB/XRF 060218, s...

A Wolf–Rayet-like progenitor of SN 2013cu from spectral observations of a stellar wind
The detection of strong emission lines in an early-time spectrum of type IIb supernova SN 2013cu reveals Wolf–Rayet-like wind signatures, suggesting that the supernova’s progenitor may have been a Wolf–Rayet s...

The superluminous transient ASASSN-15lh as a tidal disruption event from a Kerr black hole
When a star passes within the tidal radius of a supermassive black hole, it will be torn apart1. For a star with the mass of the Sun (M⊙) and a non-spinning black hole with a mass <108M⊙, the tidal radius lies ou...

Correction: Corrigendum: The superluminous transient ASASSN-15lh as a tidal disruption event from a Kerr black hole
Nature Astronomy 1, 0002 (2016); published 12 December 2016; corrected 22 December 2016. In the version of this Letter originally published the estimated energy radiated by ASASSN-15lh up to 25 May 2016 was in...

Confined dense circumstellar material surrounding a regular type II supernova
With the advent of new wide-field, high-cadence optical transient surveys, our understanding of the diversity of core-collapse supernovae has grown tremendously in the last decade. However, the pre-supernova e...

A UV resonance line echo from a shell around a hydrogen-poor superluminous supernova
Hydrogen-poor superluminous supernovae (SLSN-I) are a class of rare and energetic explosions that have been discovered in untargeted transient surveys in the past decade1,2. The progenitor stars and the physical ...
