Extract

Most supernova remnants (SNRs) show a ring-shaped radio intensity distribution which is interpreted as the projection of an approximately spherical shell of emission. However, in many cases the ring is neither circular nor complete; in this empirical investigation a major factor responsible for asymmetry is identified and the implications of this discovery are explored.
