Extract

Theoretical work on the radio emission from supernova remnants (SNRs) has not developed much since the pioneering work of Shklovsky (1960) and van der Laa (1962a, b). Despite agreement that the emission results from the synchrotron process, the origin of the relativistic particles and magnetic field is not clear. There are three reasonable alternatives:

  1. (i) particles and field originate within the ejected material (e.g. Shklovsky 1960);

  2. (ii) both field and particles originate in the compressed interstellar medium (e.g. van der Laan 1962a);

  3. (iii) the field is interstellar but the particles are from the ejecta (as outlined by van der Laan 1962b).
