AGN power versus spatial extent of the ionized gas. The black solid line corresponds to the relation predicted by Qiu et al. (2019) simulations. BGGs with P_cav estimated using their X-ray cavities properties from Kolokythas et al. (2018) are shown with red symbols. Filaments sources and compact disks are displayed with stars and circles, respectively. Yellow triangles mark the BCGs sample from Olivares et al. (2019). Rarely the points follow the correlation, thus ruling out a dominant role of AGN-outflow driven condensation.
