The X - ray afterglow of GRB 980519
Over a total of 20 gamma-ray bursts localized with arcmin accuracies, GRB980519 represents the 13 th detected by the BeppoSAX Wide Field Cameras (WFCs). An X-ray TOO observation performed by the BeppoSAX Narrow Field Instruments (NFIs), starting about 9.5 hours after the high energy event, revealed X-ray afterglow emission in the 0.1–10 keV energy range. The flux decay was particularly fast wit...
متن کاملThe X - ray afterglow of GRB 020322
The spectrum of the afterglow of GRB 020322 is the highest-quality X-ray spectrum of a GRB afterglow available to date. It was detected by XMM-Newton in an observation starting fifteen hours after the GRB with a mean 0.2–10.0 keV observed flux of 3.5 ± 0.2 × 10 −13 erg cm −2 s −1 , making it the brightest X-ray afterglow observed so far with XMM-Newton. The source faded; its lightcurve was well...
متن کاملThe X - ray afterglow of GRB 030329
the date of receipt and acceptance should be inserted later Abstract. We report on XMM-Newton and Rossi-XTE observations of the bright (fluence ∼ 10 −4 erg cm −2) and nearby (z=0.1685) Gamma-Ray Burst GRB030329 associated to SN2003dh. The first Rossi-XTE observation, 5 hours after the burst, shows a flux decreasing with time as a power law with index 0.9±0.3. Such a decay law is only marginally...
متن کاملThe GeV afterglow of GRB
We study the emission of the short/hard GRB 090510 at energies > 0.1 GeV as observed by the Large Area Telescope (LAT) onboard the Fermi satellite. The GeV flux rises in time as t 2 and decays as t −1.5 up to 200 s. The peak of the high energy flux is delayed by 0.2 s with respect to the main ∼MeV pulse detected by the Fermi Gamma Burst Monitor (GBM). Its energy spectrum is consistent with F (ν...
متن کاملTesting GRB models with the strange afterglow of GRB 090102
We present the observations of the afterglow of gamma-ray burst GRB 090102. We use optical data taken by the TAROT, REM, GROND, Palomar and NOT telescopes, and X-ray data taken by the XRT instrument on board the Swift spacecraft. This event features an unusual light curve. In X-rays, it presents a very monotonic decrease with no hint of temporal break from 0.005 to 6 days after the burst. In op...
