Sustained turbulence and magnetic energy in non-rotating shear flows
  From numerical simulations, we show that non-rotating magnetohydrodynamic
shear flows are unstable to finite amplitude velocity perturbations and become
turbulent, leading to the growth and sustenance of magnetic energy, including
large scale fields. This supports the concept that sustained magnetic energy
from turbulence is independent of the driving mechanism for large enough
magnetic Reynolds numbers.
