Relativistic Jet Formation in Microquasars
Astrophysics and Space Science, 2001Microquasars produce collimated, relativistic flow at speeds up to a Lorentz factor of ∼ 3 (0.94c). It is generally believed that such flow velocities indicate that jet acceleration and collimation occurs in the relativistic environment of a supermassive black hole.

Deceleration of relativistic jets
New Astronomy Reviews, 2003Abstract 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.

Abstract We discuss the structure and relativistic kinematics that develop in three spatial dimensions when a moderately hot, supersonic jet propagates into a denser background medium and encounters resistance from an oblique magnetic field. Our simulations incorporate relativistic MHD in a four-dimensional spacetime and clearly show that (a ...

General Relativistic Magnetohydrodynamical Models of Relativistic Jets
AIP Conference Proceedings, 2007The general relativistic magnetohydrodynamical approximation is used to study plasma flows near rotating black holes and the formation of jets. The magnetized jet from the rotating black hole is found to be efficiently accelerated to Lorentz factors of Γ ≳ 10. The magnetized jet is collimated by the corona, which has a wind component that reaches Γ ≲ 3.

Relativistic jets can be modeled as magnetohydrodynamic flows. We analyze the related equations and discuss the involved acceleration mechanisms, their relation to the collimation, to the jet confinement by its environment, and to possible rarefaction waves triggered by pressure imbalances.

Steady, Relativistic Magnetized Jet
1992The method of characteristics has been used to solve numerically the equations of steady special relativistic MHD flows. The authors show some preliminary results which investigate the effects of a dynamically important toroidal magnetic field on the propagation of weak pressure discontinuities.
