Synchrotron radiation produced by supernova remnants is generated by electrons spiraling in a magnetic field at speeds approaching the speed of light. Because these electrons exist at a wide variety of energy levels, they produce radiation across a broad spectrum.1

Synchrotron radiation from supernova remnants can include the following wavelengths:

Radio21
Infrared1
Optical (visible light)21
Ultraviolet21
X-rays1
Gamma rays1

This emission is characterized as nonthermal radiation, meaning it is not dependent on the temperature of the source. It is also typically highly polarized and continuous across these frequencies.21
