Abstract

IT is commonly assumed that a simple compression of the magnetic field occurs in interstellar shock waves. Recent space observations of the Earth's bow shock show that turbulent amplification of the magnetic field can occur in a collisionless shock. I show here that radio observations of Tycho's supernova remnant indicate the presence of a shock wave with such magnetic field amplification.
