Efficiency of the centrifugally induced curvature drift instability in AGN winds

Z. Osmanov

For studying how the field lines are twisting nearby the light cylinder surface, which provides the free motion of AGN winds through the mentioned area, the investigation of the ce…

On the linear theory of Kelvin-Helmholtz instabilities of relativistic magnetohydrodynamic planar flows

Z. Osmanov, A. Mignone, S. Massaglia +2

We investigate the linear stability properties of the plane interface separating two relativistic magnetized flows in relative motion. The two flows are governed by the (special) r…

Amplification of MHD waves in swirling astrophysical flows

Andria Rogava, Gianluigi Bodo, Silvano Massalgia +1

Recently it was found that helical magnetized flows efficiently amplify Alfvén waves (Rogava et al. 2003, A&A, v.399, p.421). This robust and manifold nonmodal effect was found to…

Centrifugally driven relativistic dynamics on curved trajectories

Andria Rogava, George Dalakishvili, Zaza Osmanov

Motion of test particles along rotating curved trajectories is considered. The problem is studied both in the laboratory and the rotating frames of reference. It is assumed that th…
