An X-ray pulsar with a superstrong magnetic field in the soft γ-ray repeater SGR1806 − 20
- C. Kouveliotou, S. Dieters, +8 authors T. Murakami
- Physics
- Nature
- 21 May 1998
Soft γ-ray repeaters (SGRs) emit multiple, brief (∼0.1-s), intense outbursts of low-energy γ-rays. They are extremely rare—three are known in our Galaxy and one in the Large Magellanic Cloud. Two… Expand
An unusual supernova in the error box of the γ-ray burst of 25 April 1998

TLDR
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
The effect of magnetic fields on γ-ray bursts inferred from multi-wavelength observations of the burst of 23 January 1999
- T. J. Galama, M. Briggs, +38 authors D. Bhattacharya
- Physics
- Nature
- 1 April 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… Expand
Infrared helium emission lines from Cygnus X-3 suggesting a Wolf-Rayet star companion
- M. Kerkwijk, P. Charles, +6 authors J. V. Paradijs
- Physics
- Nature
- 1 February 1992
CYGNUS X-3 is one of the most luminous X-ray sources in the Galaxy1,2, a bright infrared source3 and a radio source that undergoes huge outbursts4. The system is a binary, presumably a neutron star… Expand
Where is SGR 1806-20?
- K. Hurley, C. Kouveliotou, +4 authors J. V. Paradijs
- Physics
- 1 June 1999
We apply a statistical method to derive very precise locations for soft gamma repeaters using data from the interplanetary network. We demonstrate the validity of the method by deriving a 600 arcsec2… Expand
A new type of transient high-energy source in the direction of the Galactic Centre
- C. Kouveliotou, J. V. Paradijs, +5 authors W. Lewin
- Physics
- Nature
- 29 February 1996
SOURCES of high-energy (>20 keV) bursts fall into two distinct types: the non-repeating γ-ray bursters1, several thousand of which have been detected but whose origin remains unknown, and the soft… Expand
The rarity of soft γ-ray repeaters deduced from reactivation of SGR1806 – 20
- C. Kouveliotou, G. Fishman, +8 authors D. Green
- Physics
- Nature
- 10 March 1994
ONLY two different types of γ-ray transient sources are presently known: over one thousand γ-ray bursters (GRBs) and only three soft γ-ray repeaters (SGRs). The latter are distinguished by their… Expand
Centaurus X-3.
- J. Hutchings, A. Cowley, D. Crampton, J. V. Paradijs, N. White
- Physics
- 1 May 1979
Spectroscopic observations of Krzeminski's star at dispersions 25-60 A/mm are described. The primary is an evolved star of type O6-O8(f) with peculiarities, some of which are attributable to X-ray… Expand
A γ-ray burst preceded by X-ray activity
- T. Murakami, H. Inoue, +4 authors A. Yoshida
- Physics
- Nature
- 1 April 1991
GAMMA-RAY bursts remain mysterious astrophysical phenomena. The discovery of cyclotron harmonics1–3 in their spectra is strong evidence that they originate from strongly magnetized neutron stars, but… Expand
