Energy release and conversion by reconnection in the magnetotail (2008)
Magnetic reconnection is the crucial process in the release of magnetic energy previously stored in the magnetotail in association with substorms. However, energy transfer and dissipation in the...
On the propagation of bubbles in the geomagnetic tail (2008)
Birn, J., Raeder, J., Wang, Y. L., Wolf, R. A., Hesse, M.
Using three-dimensional magnetohydrodynamic simulations, we investigate the propagation of low-entropy magnetic flux tubes ("bubbles") in the magnetotail. Our simulations address fundamental...
Acceleration of oxygen ions in the dynamic magnetotail (2008)
Birn, J., Thomsen, M. F., Hesse, M.

On the cessation of magnetic reconnection (2008)
Kinetic simulations of collisionless magnetic reconnection are used to study the effect on the reconnection rate of ion density enhancements in the inflow region. The goal of the investigation is to...

Self-regulation of the reconnecting current layer in relativistic pair plasma reconnection (2008)
We investigate properties of the reconnecting current layer in relativistic pair plasma reconnection. We found that the current layer self-regulates its thickness when the current layer runs out...
