Electromagnetic radiation emitted by charged particles (usually electrons) moving at relativistic speeds in magnetic fields. This radiation is highly polarized and produces a characteristic power-law spectrum across many wavelengths.
Named after the synchrotron particle accelerator where this radiation was first observed in 1947. The term combines 'syn-' (together) and 'chronos' (time), referring to particles moving in synchrony with an accelerating electric field.
Synchrotron radiation is nature's ultimate particle accelerator! The same process that makes electrons glow in laboratory machines also powers some of the most energetic phenomena in the universe, from radio galaxies to supernova remnants, creating beautiful cosmic light shows across the entire electromagnetic spectrum.
