Recent studies have shown that the energy input from AGN feedback, when averaged over the cluster lifetime, is capable of balancing cooling losses from the cluster gas. Spitzer observations have revealed that 30-50% of BCGs in cool core clusters exhibit star formation suggesting that current AGN heating may not be sufficiently strong to prevent cooling. We propose here to observe objects with low rates of star formation to investigate the transition into a cooling phase and the physical mechanism which triggers the formation of stars in BCGs. Combining X-ray-derived gas cooling times and estimates of AGN cavity power with IR-derived star formation rates will allow us to study the entire cycle of cooling, star formation and feedback in cluster cool cores.
