TL;DR: In this paper, the authors report on an even more intense burst on August 27, 1998, from a different soft gamma repeater, which displayed a hard energy spectrum at its peak, and was followed by a ~300 s long tail with a soft energy spectrum and a dramatic 5.16 s period.
Journal ArticleDOI

Perri,G. Tagliaferri +41 more
TL;DR: In this paper, the authors present observations of GRB 060124, the first event for which both the prompt and the afterglow emission could be observed simultaneously and in their entirety by the three Swift instruments.
Journal ArticleDOI
Konus-W gamma-ray burst experiment for the GGS Wind spacecraft
R. L. Aptekar,D. D. Frederiks,S. Golenetskii,V. N. Ilynskii,E. P. Mazets,V. N. Panov,Z. J. Sokolova,M. M. Terekhov,L. O. Sheshin,Thomas L. Cline,D. E. Stilwell +10 more
TL;DR: The Konus-W experiment as discussed by the authors was designed to observe gamma-ray bursts and solar flares with moderate spectral and high time resolution, and two large scintillators were used to provide omnidirectional sensitivity.
Journal ArticleDOI
Cyclotron and annihilation lines in γ-ray bursts
TL;DR: In this paper, the authors present results of a comprehensive analysis that included weaker bursts, which indicate that the presence of lines in the γ-burst spectra is a characteristic rather than an exceptional feature.
Journal ArticleDOI
A peculiar hard X-ray counterpart of a Galactic fast radio burst
A. Ridnaia,Dmitry S. Svinkin,D. D. Frederiks,Andrei M. Bykov,Sergei Popov,Sergei Popov,R. L. Aptekar,S. V. Golenetskii,A. Lysenko,A. Tsvetkova,M. Ulanov,T. L. Cline +11 more
TL;DR: In this paper, the authors reported the detection with Konus-Wind of a hard X-ray event of 28 April 2020 temporally coincident with a bright, two-peak radio burst in the direction of the Galactic magnetar SGR 1935+2154, with properties remarkably similar to those of FRBs.
