Three-Dimensional Relativistic Magnetohydrodynamic Simulations of Current-Driven Instability with A Sub-Alfvenic Jet: Temporal Properties
TL;DR: In this article, the influence of a velocity shear surface on the linear and nonlinear development of the current-driven kink instability of force-free helical magnetic equilibria in three dimensions is investigated.

Three-dimensional relativistic magnetohydrodynamic simulations of current-driven instability. ii. relaxation of pulsar wind nebula
TL;DR: In this paper, the authors investigated the relaxation of a hydrostatic hot plasma column containing toroidal magnetic field by the current-driven kink instability as a model of pulsar wind nebulae.
Journal ArticleDOI
Spatial Growth of the Current-driven Instability in Relativistic Jets
TL;DR: In this paper, the influence of velocity shear and a radial density profile on the spatial development of the current-driven (CD) kink instability along helically magnetized relativistic jets via three-dimensional magnetohydrodynamic simulations was investigated.
