head-tail galaxy

A head-tail galaxy is a radio galaxy whose emission has been distorted by the movement of the parent galaxy, a giant elliptical, through the intracluster medium. The result is strong radio emission coming from a bright "head" and more diffuse emission from a diffuse "tail" that stretches behind for hundreds of thousands of light-years.
