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: strongly magnetized neutron stars with emissions powered by the dissipation of magnetic energy. Here we report the detection of a long (380 s) giant flare from SGR 1806–20, which was much more luminous than any previous transient event observed in our Galaxy. (In the first 0.2 s, the flare released as much… Expand

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). SGRs… Expand
Astrophysics: A certain flare
TLDR
Five papers in this issue report initial and follow-up observations of SGR1806–20, a soft γ-ray repeater in Sagittarius, which released a giant flare that has been called the brightest explosion ever recorded. Expand
A bright γ-ray flare interpreted as a giant magnetar flare in NGC 253
TLDR
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
The Gamma-Ray Giant Flare from SGR 1806?20: Evidence of Crustal Cracking via Initial Timescales
Soft γ-ray repeaters (SGRs) are neutron stars that emit short (1 s) and energetic (1042 ergs s-1) bursts of soft γ-rays. Only four of them are currently known. Occasionally, SGRs have been observed… Expand
An expanding radio nebula produced by a giant flare from the magnetar SGR 1806–20
TLDR
From day 6 to day 19 after the flare from SGR 1806 - 20, a resolved, linearly polarized, radio nebula was seen, expanding at approximately a quarter of the speed of light, and to create this nebula, at least 4 × 1043 ergs of energy must have been emitted by the giant flare. Expand
Soft gamma-ray repeater giant flares in the BATSE short gamma-ray burst catalogue: constraints from spectroscopy
The giant flare observed on 2004 December 27 from SGR 1806−20 has revived the idea that a fraction of short (<2 s) gamma-ray bursts (GRBs) are due to giant flares from soft gamma-ray repeaters (SGRs)… Expand
The Giant Flare From SGR 1806-20 And Its Radio Afterglow
The multi-wavelength observations of the 2004 December 27 Giant Flare (GF) from SGR 1806-20 and its long-lived radio afterglow are briefly reviewed. The GF appears to have been produced by a dramatic… Expand
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 a… Expand
Quiet but still bright: XMM-Newton observations of the soft gamma-ray repeater SGR0526-66
SGR 0526–66 was the first soft gamma-ray repeater from which a giant flare was detected in 1979 March, suggesting the existence of magnetars, i.e. neutron stars powered by the decay of their… Expand
An X-ray burst from a magnetar enlightening the mechanism of fast radio bursts
Fast radio bursts (FRBs) are short (millisecond) radio pulses originating from enigmatic sources at extragalactic distances so far lacking a detection in other energy bands. Magnetized neutron stars… Expand

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 long… Expand

Gamma-ray bursts from extragalactic Magnetar Flares
The prototype for events that we call MFs—“March Fifth” events or “Magnetar Flares”—was observed on March 5, 1979. There is evidence that MFs are powered by catastrophic magnetic instabilities in… Expand
An X-ray pulsar with a superstrong magnetic field in the soft γ-ray repeater SGR1806 − 20
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
Detection of a radio counterpart to the 27 December 2004 giant flare from SGR 1806–20
TLDR
The energetics and the rapid decay of the radio source are not compatible with the afterglow model that is usually invoked for γ-ray bursts, and it is suggested that the rapidly decaying radio emission arises from the debris ejected during the explosion. Expand
