Electron Acceleration in Supernovae and Millimeter Perspectives by Keiichi Maeda

“…I argue that the eciency of the acceleration at the young SN shock is much lower than conventionally assumed, and that the electrons emitting in the<em> cm</em> wavelengths are <em>not</em> fully in the Diffusive Shock Acceleration (DSA) regime. Thus radio emissions from young SNe record information on the yet-unresolved 'injection' mechanism. …”
