Plasma Waves and Instabilities at Comets and in Magnetospheres
The propagation of dense energetic neutralized ion beams or plasmoids injected into a plasma across the ambient magnetic field under ionospheric conditions is considered. Using a simple physical model supported by two-dimensional hybrid simulations,

A linear analysis is performed to investigate the kinetic cross-field streaming instability in the earth's magnetotail neutral sheet region. Numerical solution of the dispersion equation shows that the instability can occur under conditions expected

In this paper we show how SAVS, a tool for visualization and data analysis in space and atmospheric science, can be used to quickly and easily address problems that would previously have been far more laborious to solve. Based on the popular AVS pack
