Abstract. Supermassive black holes (SMBHs) play key roles in galaxy and cluster evolution. This is most clearly seen in the “fossil record” that is imprinted in the gas rich atmospheres of early type galaxies, groups, and clusters by powerful SMBH outbursts. I will discuss the outburst history of M87 as chronicled in its radio and X-ray images and the implications of these outbursts for heating gas rich environments. Based on a simple shock model of M87’s 12 Myr old outburst, I will present the properties of the outburst including its age, total energy, and duration. In addition to discussing the outburst around M87, I will review the results of a galaxy survey that shows the effects of SMBH feedback on early type galaxies and has interesting implications for the growth of SMBHs over cosmic time. I conclude by describing a future X-ray mission, Lynx, whose sub-arcsecond angular resolution would allow us to study the evolution of SMBHs and hot, X-ray emitting atmospheres from high redshifts to the present.
