Highly-luminous cool core clusters of galaxies require extreme mechanical feedback from their central AGN to offset cooling of the intracluster plasma (L_mech>1045 erg/s). These systems therefore provide a unique opportunity to study the extreme side of AGN feedback, noticeably through the properties of their AGN outflows, known as X-ray cavities. I present work examining X-ray cavities in such systems.
More precisely, I present the first statistical study of X-ray cavities in distant clusters of galaxies (z>0.3). With the aim of providing further insight into how AGN feedback operates at higher redshift, I have analysed the Chandra X-ray observations of the Massive Cluster Survey (MACS). This sample consists of highly-luminous clusters of galaxies within 0.31045 erg/s) starts to operate as early as 7-8 Gyr after the Big Bang and shows no sign of evolution since then. These results have important ramifications for galaxy formation and evolution models.
I also discuss the implications these results have with regards to the masses of the black holes that power these outbursts, and provide evidence that some may be ultramassive (>1010 Msol) as oppose to supermassive (109 Msol).
