Abstract (from CDS):

We present the results of our study of a volume-limited sample (z ≤ 0.071) of 101 X-ray galaxy groups and clusters, in which we explore the X-ray cavity energetics. Out of the 101 sources in our parent sample, X-ray cavities are found in 30 of them, all of which have a central cooling time of ≤ 3 Gyr. New X-ray cavities are detected in three sources. We focus on the subset of sources that have a central cooling time of ≤ 3 Gyr, whose active galactic nucleus (AGN) duty cycle is ≃ 61 percent (30/49). This rises to >80 percent for a central cooling time of ≤ 0.5 Gyr. When projection effects and central radio source detection rates are considered, the actual duty cycle is probably much higher. In addition, we show that data quality strongly affects the detection rates of X-ray cavities. After calculating the cooling luminosity and cavity powers of each source with cavities, it is evident that the bubbling process induced by the central AGN has to be, on average, continuous, to offset cooling. We find that the radius of the cavities, r, loosely depends on the ambient gas temperature as r ∝ T0.5, above about 1.5 keV, with much more scatter below that temperature. Finally, we show that, at a given location in a group or cluster, larger bubbles travel faster than smaller ones. This means that the bubbles seen at larger distances from cluster cores could be the result of the merging of several smaller bubbles, produced in separate AGN cycles.
