Particle Acceleration in Galactic Supernova Remnants
Abstract
This paper discusses the radio spectral indices of Galactic SNRs in relation to the particle acceleration mechanisms responsible for their radio emission. Young, bright shell remnants generally have spectral indices α larger than the 0.5 expected from basic shock acceleration theory. Fainter, older shell remnants have a wide range of α. Evidence on whether or not particle acceleration is continuing in SNRs is also discussed.
