  journal={The Astrophysical Journal},
The light curve, energy spectra, energetics, and IPN localization of an exceedingly intense, short-duration, hard-spectrum burst, GRB 070201, obtained from Konus-Wind, INTEGRAL (SPI-ACS), and MESSENGER data are presented. The total fluence of the burst and the peak flux are -->S = 2.00+ 0.10−0.26 × 10−5 erg cm−2 and -->Fmax = 1.61+ 0.29−0.50 × 10−3 erg cm−2 s−1. The IPN error box has an area of 446 arcmin2 and covers the peripheral part of the M31 galaxy. Assuming that the source of the burst… Expand

GRB 070201: a possible soft gamma-ray repeater in M31
GRB 070201 was a bright, short-duration, hard-spectrum gamma-ray burst detected by the Interplanetary Network. Its error quadrilateral, which has an area of 0.124 deg 2 , intersects some prominentExpand
The Ultraluminous GRB 110918A
GRB 110918A is the brightest long gamma-ray burst (GRB) detected by Konus-WIND during its almost 19 yr of continuous observations and the most luminous GRB ever observed since the beginning of theExpand
GRB 200415A: Magnetar Giant Flare or Short Gamma-Ray Burst?
A detailed analysis of the GBM/Fermi experiment data is carried out to classify GRB 200415A. It is shown that, on the one hand, this event exhibits typical for type I (short) gamma-ray bursts (GRBs)Expand
Rapid spectral variability of a giant flare from a magnetar in NGC 253
Observations of the γ-ray burst GRB 200415A have a rapid onset, very fast time variability, flat spectra and substantial sub-millisecond spectral evolution, which match well with those expected for a giant flare from an extragalactic magnetar. Expand
A search for giant flares from soft gamma-ray repeaters in nearby galaxies in the Konus-WIND short burst sample
The knowledge of the rate of soft gamma-ray repeater (SGR) giant flares is important for understanding the giant flare mechanism and the SGR energy budget in the framework of the magnetar model. WeExpand
A new analysis of the short-duration, hard-spectrum GRB 051103, a possible extragalactic soft gamma repeater giant flare
GRB 051103 is considered to be a candidate soft gamma repeater (SGR) extragalactic giant magnetar flare by virtue of its proximity on the sky to M81/M82, as well as its time history, localization andExpand
GRB 200415A: A Short Gamma-Ray Burst from a Magnetar Giant Flare?
The giant flares of soft gamma-ray repeaters (SGRs) have long been proposed to contribute to at least a subsample of the observed short gamma-ray bursts (GRBs). In this paper, we perform aExpand
Unveiling the Origin of Grb 090709A: Lack of Periodicity in a Reddened Cosmological Long-Duration Gamma-Ray Burst
We present broadband (gamma-ray, X-ray, near-infrared, optical, and radio) observations of the Swift gamma-ray burst (GRB) 090709A and its afterglow in an effort to ascertain the origin of thisExpand
Multiwavelength Observations of Fast Radio Bursts
The origin and phenomenology of the Fast Radio Burst (FRB) remains unknown in spite of more than a decade of efforts (see [1–5] for a review). Though several models have been proposed to explain theExpand
A bright γ-ray flare interpreted as a giant magnetar flare in NGC 253
The γ-ray burst GRB 200415A is probably a giant flare emitted from a magnetar in the nearby starburst galaxy NGC 253, located about 3.5 million parsecs away. Expand


Unusual Burst Emission from the New Soft Gamma Repeater SGR 1627–41
In 1998 June-July, the Konus-Wind burst spectrometer observed a series of bursts from the new soft gamma repeater SGR 1627-41. Time histories and energy spectra of the bursts have been studied,Expand
An exceptionally bright flare from SGR 1806–20 and the origins of short-duration γ-ray bursts
Soft-γ-ray repeaters (SGRs) are galactic X-ray stars that emit numerous short-duration (about 0.1 s) bursts of hard X-rays during sporadic active periods. They are thought to be magnetars: stronglyExpand
Giant flare in SGR 1806-20 and its Compton reflection from the Moon
We analyze the data obtained when the Konus-Wind gamma-ray spectrometer detected a giant flare in SGR 1806-20 on December 27, 2004. The flare is similar in appearance to the two known flares in SGRExpand
A giant periodic flare from the soft γ-ray repeater SGR1900+14
Soft γ-ray repeaters are transient sources of high-energy photons; they emit sporadic and short (about 0.1 s) bursts of ‘soft’ γ-rays during periods of activity, which are often broken by longExpand
The Quiescent Counterpart of the Soft Gamma-Ray Repeater SGR 0526–66
It is now commonly believed that soft gamma-ray repeaters (SGRs) and anomalous X-ray pulsars (AXPs) are magnetars—neutron stars powered by their magnetic fields. However, what differentiates theseExpand
A giant γ-ray flare from the magnetar SGR 1806–20
Two classes of rotating neutron stars—soft γ-ray repeaters (SGRs) and anomalous X-ray pulsars—are magnetars, whose X-ray emission is powered by a very strong magnetic field (B ≈ 1015 G). SGRsExpand
Soft Gamma-Ray Repeaters in Nearby Galaxies: Rate, Luminosity Function, and Fraction among Short Gamma-Ray Bursts
It was suggested that some of the short-duration gamma-ray bursts (GRBs) are giant flares of soft gamma-ray repeaters (SGRs) in nearby galaxies. To test this hypothesis, I have constructed a sampleExpand
The Gamma-Ray Giant Flare from SGR 1806?20: Evidence of Crustal Cracking via Initial Timescales
