Radio Sources in Clusters

• Radio sources and the X-ray emitting ICM have a profound effect on each other, as seen with Chandra. Radio sources blow bubbles in the ICM and the ICM confines and distorts the radio lobes.

• 70% of cooling flow clusters contain central cD galaxies with associated radio sources, and 20% of non-cooling flow clusters have radio-bright central galaxies.

• The fact that radio sources are distorted by dense ICM can be exploited to find high-z clusters using radio sources as tracers.
