MHD Simulations of Relativistic Jets

Astrophysics and Space Science, 2004
In a series of time dependent numerical simulations we have performed a parameter study of magnetised relativistic jets. We have found that the impact of the magnetic field on the morphology of a jet depends strongly on the configuration of the field.

Deceleration of relativistic jets

New Astronomy Reviews, 2003
Abstract There are now good evidences that, on the parsec scale, jets are relativistic also in Fanaroff–Riley I radiogalaxies. On the other hand they are likely to be subrelativistic on larger scale. Here we present preliminary results of numerical simulations of relativistic jets, whose purpose is the analysis of this deceleration process.

Magnetohydrodynamic Production of Relativistic Jets

Science, 2001
A number of astronomical systems have been discovered that generate collimated flows of plasma with velocities close to the speed of light. In all cases, the central object is probably a neutron star or black hole and is either accreting material from other stars or is in the initial violent stages of formation.

Relativistic Jet Simulations

Astrophysics and Space Science, 1994
Observations on parsec scales suggest that the flow in extra-galactic radio sources has both bulk and thermal Lorentz factors which are significantly greater than one. Using a simple transformation of variable, Chiu (1973) demonstrated that the dynamical equations for a relativistic, nondegenerate fluid (Synge (1957)), can be expressed in a form which ...

Stability of a Relativistic Half-Jet

The Physics of Fluids, 1967
The stability of an inviscid compressible relativistic half-jet is considered. Linearized disturbance equations are obtained for three-dimensional, infinitesimal, wavy disturbances superimposed on the main flow and the eigenvalue problem is investigated numerically for the case of two-dimensional disturbances.

ON MAGNETIC SELF-COLLIMATION OF RELATIVISTIC JETS

International Journal of Modern Physics D, 2010
We present a semi-analytical model using the equations of general relativistic magnetohydrodynamics (GRMHD) for jets emitted by a rotating black hole. We assume steady axisymmetric outflows of a relativistic ideal fluid in Kerr metrics. We express the conservation equations in the frame of the FIDucial Observer (FIDO or ZAMO) using a 3+1 space–time ...
