Examples of use of GRB
1. The September 4 burst, named GRB 050'04, has a redshift of 6.2', which translates to a distance of about 13 billion light–years from Earth.
2. The blast is thought to be a milder type of gamma–ray burst (GRB) –– the most powerful type of explosion known to astronomers –– called an X–ray flash.
3. "All four papers make clear that the exploding object sent out both a slightly aspherical shockwave, typical of a supernova, and a jet–like stream of material characteristic of a GRB," he said.
4. Scientists led by Paolo Mazzali, of the Max Planck Institute of Astrophysics in Garching, Germany found that the star had a smaller mass than those estimated for the normal GRB–supernova.
5. "This extends the GRB–supernova connection to X–ray flashes and fainter supernovae, implying a common origin," said Elena Pian of Italy‘s National Institute for Astrophysics in Trieste and the lead author of one of four research papers about the event in the journal Nature on Wednesday.
