Strong Relativistic Collisionless Shock
A direct numerical simulation of a strong relativistic collisionless shock propagating into an unmagnetized medium has been performed in two spatial dimensions. It is found that: (i) collisionless shock exists, (ii) particle acceleration is insignificant, (iii) the shock does not generate “quasi-static” magnetic fields, contrary to recent claims by other authors. All our results agree with a si...
متن کاملHarris sheet solution for magnetized quantum plasmas
We construct an infinite family of one-dimensional equilibrium solutions for purely magnetized quantum plasmas described by the quantum hydrodynamic model. The equilibria depends on the solution of a third-order ordinary differential equation, which is written in terms of two free functions. One of these free functions is associated to the magnetic field configuration, while the other is specif...
متن کاملSheared-flow Generalization of the Harris Sheet
A novel, exact class of solutions to the Vlasov–Maxwell system, with self– generated magnetic fields and nonuniform plasma flows, are constructed. It is shown that a gyrotropic distribution function (independent of gyrophase) does not allow equilibrium shear flow; introduction of agyrotropy is essential for the maintenance of spatially nonuniform velocity fields. The new self–consistent sheared...
متن کاملStability of Relativistic Force-free Jets
We consider a two-parameter family of cylindrical force-free equilibria, modeled to match numerical simulations of relativistic force-free jets. We study the linear stability of these equilibria, assuming a rigid impenetrable wall at the outer cylindrical radius R j. We find that equilibria in which the Lorentz factor γ(R) increases monotonically with increasing radius R are stable. On the othe...
متن کاملImbalanced Relativistic Force-free Magnetohydrodynamic Turbulence
When magnetic energy density is much larger than that of matter, as in pulsar/black hole magnetospheres, the medium becomes force-free and we need relativity to describe it. As in non-relativistic magnetohydrodynamics (MHD), Alfvénic MHD turbulence in the relativistic limit can be described by interactions of counter-traveling wave packets. In this paper we numerically study strong imbalanced M...
