Abstract
New radio data and a critical examination of the interacting galaxies hypothesis to explain complex radio sources in clusters lead us to reject a causal relation between sources in clusters. Instead, the “head–tail” radio galaxies are proposed to represent radio trails of galaxies, active in their own right, along trajectories through a dense intergalactic medium.
