The polarization of core-collapse supernovae shows that many if not all of these explosions must be strongly bi-polar. The most obvious way to produce this axial symmetry is by the imposition of a jet as an intrinsic part of the explosion process. These jets could arise by MHD processes in the formation of pulsars and be especially strong in the case of magnetars. The jets will blow iron-peak m...
متن کاملSGR giant flares in the BATSE short GRB catalogue: constraints from spectroscopy
The giant flare observed on Dec. 27 2004 from SGR 1806–20 has revived the idea that a fraction of short (<2 s) Gamma Ray Bursts (GRB) is due to giant flares from Soft Gamma Ray Repeaters located in nearby galaxies. One of the distinguishing characteristics of these events is the thermal (black body) spectrum with temperatures ranging from ∼50 to ∼180 keV, with the highest temperature observed f...
متن کاملBATSE Observations of Gamma-Ray Burst Tails
With the discovery of low-energy radiation appearing to come from the site of gamma-ray bursts in the hours to weeks after the initial burst of gamma rays, it would appear that astronomers have seen a cosmological imprint made by the burster on its surroundings. I discuss in this paper the phenomenon of post-burst emission in BATSE gamma-ray bursts at energies traditionally associated with prom...
متن کاملPure and Loaded Fireballs in Soft Gamma-ray Repeater Giant Flares
On December 27, 2004, a giant flare from SGR 1806−20 was detected on earth. Its thermal spectrum and temperature suggest that the flare resulted from an energy release of about 1047 erg/sec close to the surface of a neutron star in the form of radiation and/or pairs. This plasma expanded under its own pressure producing a fireball and the observed gamma-rays escaped once the fireball became opt...
متن کاملGiant Flares as Mini Gamma Ray Bursts
On December 27, 2004, practically all gamma-ray satellites were saturated by a giant flare from SGR1806−20 (Borkowski et al. 2004; Hurley et al. 2004; Mazets et al. 2004). This giant flare was strong enough to affect our ionosphere (Campbell et al. 2005) and for its reflection from the moon to be detected (Golenetskii et al. 2004). It was followed by an extremely bright radio afterglow, with an...
