Projects:

  1. Relativistic jets in GRBs:
    This are some gifs of my current work in relativistic simulations of GRBs in collaboration with Ewald Muller, Jose M. Marti and J.M. Ibanez. Initial models where calculated by Andrew MacFadyen and Stan E. Woosley (see astro-ph/9810274) using a two-dimensional (newtonian) hydrodynamics code (PROMETHEUS).
    1. Progenitors of Long GRBs (collapsar models)
    2. Progenitors of Short GRBs (collapsar models)
    3. Newest results: Movie showing a volume rendering of a ultrarelativistic jet generated after the merger of a pair of compact objects.
  2. Relativistic Jets from AGNs and Microquasars: This are some gif files of my research in: "High-resolution 3D simulations of relativistic jets". The work is being done in collaboration with: J.M. Marti, J.M.Ibanez, J.L. Gomez and E. Mueller.

Progenitors of Short GRBs (collapsar models)

Movies:
These movies show the evolution of the ultrarelativistic jets and of the accretion torus. In case A energy is released at the black hole only for a tenth of a second and in case B the energy release is continuous, but decreasing steeply with time.
