Scientists have recently identified electrons and positrons with the highest energies ever recorded on Earth. They provide evidence of cosmic processes emitting colossal amounts of energy, the origins...
Electron acoustic solitary waves with non-thermal distribution of electrons
Electron acoustic solitary waves non-thermal distribution of electrons
2009/11/11
Electron-acoustic solitary waves are studied in an unmagnetized plasma consisting of non-thermally distributed electrons, fluid cold electrons and ions. The Sagdeev pseudo-potential technique is used ...
The formation of relativistic plasma structures and their potential role in the generation of cosmic ray electrons
