cds-question@unistra.frgalaxy-clustersradio-galaxiesradio-continuum-emissionWe present an analysis of the energetics and particle content of the lobes of 24 radio galaxies at the cores of cooling clusters. The radio lobes in these systems have created visible cavities in the surrounding hot, X-ray-emitting gas, which allow direct measurement of the mechanical jet power of radio sources over six decades of radio luminosity, independently of the radio properties themselves. We find that jet (cavity) power increases with radio synchrotron power approximately as P_jet_~L^{beta}^_radio_, where 0.35<={beta}<=0.70 depending on the bandpass of measurement and state of the source. Furthermore, we place limits on the magnetic field strengths and particle content of the radio lobes using a variety of X-ray constraints. We find that the lobe magnetic field strengths vary between a few to several tens of microgauss depending on the age and dynamical state of the lobes.2008ApJ...686..859Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/686/859CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/130/1977 : FIRST-Optical-VLA survey for lensed radio lobes (Haarsma+,J/AJ/109/853 : VLA survey of Abell clusters.
