synchrotron radiation
  • Radiation emitted by charged particles travelling at speeds near that of light through magnetic fields, and observable in both optical and radio astronomy. Electrons travelling at near-light speeds in strong magnetic fields are the usual source of synchrotron radiation in astronomy.
  • The electromagnetic radiation emitted by charged particles which are moving within a magnetic field at speeds approaching that of light. This is observed, for instance, in a synchrotron.
