Relativistic Jets from Collapsars
Miguel A. Aloy, Ewald Mueller, Jose M. Ibanez +2
We have studied the relativistic beamed outflow proposed to occur in the collapsar model of gamma-ray bursts. A jet forms as a consequence of an assumed energy deposition of $\sim…

Simulations of Relativistic Jets with GENESIS
Miguel A. Aloy, Jose M. Ibanez, Jose M. Marti +2
The multidimensional relativistic hydrodynamical code GENESIS has been used to obtain first results of {\it 3D} simulations of relativistic jets. We have studied the influence of a…

An exact Riemann Solver for multidimensional special relativistic hydrodynamics
J. Pons, J. Ma. Marti, E. Muller
We have generalised the exact solution of the Riemann problem in special relativistic hydrodynamics for arbitrary tangential flow velocities. The solution is obtained by solving th…
