Tracing Ghost Cavities with Low Frequency Radio Observations [PDF]

, 2006
We present X-ray and multi-frequency radio observations of the central radio sources in several X-ray cavity systems. We show that targeted radio observations are key to determining if the lobes are being actively fed by the central AGN.
