Line emission from gamma-ray burst environments

  title={Line emission from gamma-ray burst environments},
  author={Markus B{\"o}ttcher},
The time and angle dependent line and continuum emission from a dense torus around a cosmological gamma-ray burst source is simulated, taking into account photoionization, collisional ionization, recombination, and electron heating and cooling due to various processes. The importance of the hydrodynamical interaction between the torus and the expanding blast wave is stressed. Due to the rapid deceleration of the blast wave as it interacts with the dense torus, the material in the torus will be… CONTINUE READING
