Radio Sources as Tracers of Distant Clusters

Since the appearance of radio sources is affected by interaction with the ICM (confinement, distortion), we can use radio sources to locate distant clusters of galaxies that would be difficult to find in optical (b.c. of projection effects) or X-ray (b.c. of flux limits) surveys.
