Accretion rates and energy injection of the AGN hosted in the centres on BCGs. Cool-core clusters are shown in blue, and hot-core clusters are shown in orange. Solid lines indicate moving medians, and dashed lines represent 16% and 84% percentiles (1σ) from the Magneticum simulation (Box2b/hr). Observational data is shown with error bars at the 1σ level. Left panel: Comparison of the accretion rates from the AGN hosted in the centres on BCGs, with the estimations from Fujita et al. (2014) and Russell et al. (2013). Right panel: Comparison of black hole energy injection with the observational estimations from Rafferty et al. (2006), Russell et al. (2013), Eckert et al. (2021) and Pasini et al. (2022).
