Energetic feedback from supermassive black holes is thought to be responsible for preventing star formation in massive galaxies, including our own Milky Way. The most massive galaxies in the Universe, which live at the centers of galaxy clusters, provide a unique, “high-contrast” opportunity to study the details of this feedback. I will present a summary of work from our group studying the limitations and details of black hole feedback in massive galaxies, the evolution of the cooling/feedback balance over ~10 Gyr, and what we have learned about lower-mass galaxies by studying these most-massive systems. I will finish with a summary of other cluster research, and a look ahead to the future of research in this field.
