N ov 1 99 8 Reactivation and Precise IPN Localization of the Soft Gamma Repeater SGR 1900 + 14
نویسندگان
چکیده
In 1998 May, the soft gamma repeater SGR1900+14 emerged from several years of quiescence and emit a series of intense bursts, one with a time history unlike any previously observed from this source. Triangulation using Ulysses , BATSE, and KONUS data give a 1.6 square arcminute error box near the galactic supernova remnant G42.8+0.6. This error box contains a quiescent soft X-ray source which is probably a neutron star associated with the soft repeater.

متن کاملD ec 1 99 8 A relativistic particle outburst from the soft gamma - ray repeater 1900 + 14
Soft gamma-ray repeaters (SGR) are a class of high energy transients whose brief emissions are thought to arise from young 1 and highly magnetized neutron stars 2,3,4,5,6. The exact cause for these outbursts and the nature of the energy loss remain unknown. Here we report the discovery of a fading radio source within the localization of the relatively under-studied SGR 1900+14. We argue that th...

A ∼50 ks XMM-Newton observation of SGR 1900+14 has been carried out in September 2005, after almost three years during which no bursts were detected from this soft gamma-ray repeater. The 0.8-10 keV spectrum was well fit by a power law plus blackbody model with photon index Γ=1.9±0.

We present evidence for burst emission from SGR 1900+14 with a power-law high energy spectrum extending beyond 500 keV. Unlike previous detections of high energy photons during bursts from SGRs, these emissions are not associated with high-luminosity burst intervals. Not only is the emission hard, but the spectra are better fit by Band’s GRB function rather than by the traditional optically-thi...
