The Influence of Helical Magnetic Fields in the Dynamics and Emission of Relativistic Jets
M. Roca-Sogorb, M. Perucho, J. L. Gomez +4
We present numerical relativistic magnetohydrodynamic and emission simulations aimed to study the role played by the magnetic field in the dynamics and emission of relativistic jet…
Relativistic Outflows in Gamma-Ray Bursts
M. A. Aloy, M. Obergaulinger
The possibility that gamma-ray bursts (GRBs) were not isotropic emissions was devised theoretically as a way to ameliorate the huge energetic budget implied by the standard firebal…
Polarimetric VLBI observations of 0735+178
I. Agudo, J. L. Gomez, D. C. Gabuzda +5
We present a new centimeter polarimetric VLBI image of the BL Lac object 0735+178. This source exhibits one of the most pronounced curvatures observed in jets of AGNs, with two sha…
Riemann Solvers in General Relativistic Hydrodynamics
J. M. Ibanez, M. A. Aloy, J. A. Font +3
Our contribution concerns with the numerical solution of the 3D general relativistic hydrodynamical system of equations within the framework of the 3+1 formalism. We summarize the…
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…
