Modern astronomy seeks to understand how galaxies seen in the local Universe formed in the thirteen billion years since the Big Bang. Computer simulations can successfully reproduce the structure of the Universe on large scales but typically fail when we zoom in on individual galaxies. In particular, the largest galaxies are predicted to be awash with cold gas and young stars, when in reality they are gas-poor and dormant. Additional physics is needed. Known as feedback, the high-energy processes around supermassive black holes are thought to drive gas out of galaxies and shut down star formation. These black holes lie at the centre of every galaxy, including our Milky Way, but we do not yet understand how they can limit the growth of an entire galaxy. I will review our understanding of feedback, our recent discoveries with current telescopes and the exciting potential of the newly launched XRISM observatory.
