متن کاملHETE Observations of GRB 010921
On September 21 at 18950.56 SOD (05:15:50.56) UT the FREGATE γ-ray instrument on the High Energy Transient Explorer (HETE) detected a bright gamma-ray burst (GRB). The burst was also seen by the X-detector on the WXM X-ray instrument and was therefore well-localized in the X direction; however, the burst was outside the fully-coded field-of-view of the WXM Y-detector, and therefore information ...
متن کاملGRB 010921: Discovery of the First HETE Afterglow
We present the discovery of the optical and radio afterglow of GRB 010921, the first gamma-ray burst afterglow to be found from a localisation by the High Energy Transient Explorer satellite. Discovery of the afterglow enabled us to determine the redshift, z = 0:45092 from the host galaxy. We expect that the low redshift of this GRB will enable the strongest limits on the detection of an underl...
متن کاملThe GRB-Supernova Connection
Long-duration gamma-ray bursts (GRBs) are believed to be produced by the core collapse of massive stars and hence to be connected with supernovae (SNe). Indeed, for four pairs of GRBs and SNe, spectroscopically confirmed connection has been firmly established. For more than a dozen of GRBs the SN signature (the ‘red bump’) has been detected in the afterglow lightcurves. Based on the four pairs ...
متن کاملObserving supernova 1987A with the refurbished Hubble Space Telescope.
Observations with the Hubble Space Telescope (HST), conducted since 1990, now offer an unprecedented glimpse into fast astrophysical shocks in the young remnant of supernova 1987A. Comparing observations taken in 2010 with the use of the refurbished instruments on HST with data taken in 2004, just before the Space Telescope Imaging Spectrograph failed, we find that the Lyα and Hα lines from sho...
