… cluster cores with distinct radio bubbles, adding more active bubbles, ie those with GHz radio
emission, to our sample and also investigating ‘ghost bubbles’, ie those without GHz radio …

… We point out that a super-Alfvenic motion of a plasma cloud (a core of a merging galaxy)
through … Similar effects occur for radio bubbles, quasi-spherical expanding cavities blown up by …

… the inner cluster region than rarer large outbursts. Moreover, we computed radio maps of
the bubbles based on … In the radio band the bubbles closely resemble FR I sources. For the …

… X-ray deficit and for the radio spectrum of a buoyantly rising bubble. The aim of this work is
… of X-ray and radio observations of galaxy clusters. We show that the cluster volume tested for …

… of these hot plasma bubbles in FR II … bubbles as they become subject to Rayleigh–Taylor
instabilities. From our simulations we calculate the radio and X-ray emissivities of the bubbles …

… that the radio emitting regions interact with the ICM. This interaction is indeed observed in
tailed radio galaxies, and radio sources filling X-ray cavities at the center of cool-core clusters (…

… ABSTRACT In order to better understand the origin and evolution of relic radio bubbles in
clusters of galaxies, we report on an extensive set of two-dimensional MHD simulations of hot …
