Definition

Gamma Ray Bursts or GRB’s are created by shockwaves in the jets of matter that are being ejected from black holes.

how grb s form
How GRB’s Form
  • When a black hole forms, especially if it is formed from the collision of two neutron stars remaining matter and debris will settle in a disk around the black hole.
  • As this matter gets slowly sucked into the black hole the magnetic field will shoot some of the matter away 2 jets each aiming in the opposite direction of the other.
  • GRB’s are formed from the immense shock waves that are known to take place within these jets.

Longer GRB’s
  • The second kind of GRB is one in which each burst lasts longer then 2 seconds.
  • Instead of coming from the collision of 2 neutron starts these longer GRB’s are accredited to massive stellar explosions.

  • The main way we can see both long or short GRB’s is through the massive amounts of radiation that they give of.
  • They can also sometimes be tracked by the gravitational wave that the create while flaring.

  • In a Few Words…
  • Gamma-ray bursts were not understood until a few months ago when scientists discoveries that GRB’s were ignited by the collision of two neutron stars or a neutron star and a black hole. However, more recent observations show that these rays are much more complex than they were imagined to be. When two objects collide, they collapse into a black hole. Shorter rays didn’t cooperate with this theory and scientists saw that each of these ray bursts were followed by x-ray flares. Scientists were confused by the contrasting lengths of the rays. Many astronomers were convinced that short GRBs are ignited by the catastrophic merger of two neutron stars, or a neutron star and a black hole. The mystery of gamma-ray bursts has yet to be completely revealed.
