Magnetic Field Amplification in Turbulent Shear Flows |
|
Abstract |
The origin of large scale magnetic fields in a variety of astrophysical outflows has remained a mystery. I will present high resolution three-dimensional relativistic magnetohydrodynamical (RMHD) simulations of shear instabilities and ensuing turbulence. We have computed the power spectrum of mildly relativistic 3D MHD turbulence at a resolution of 1024 cubed which will be presented. The model amplifies weak seed magnetic field to values of one half of a percent (0.005) of the total energy density. I will also discuss charged test particle acceleration in shearing turbulent flows. |
