Description
Feedback between supermassive black holes (SMBH) and their
host galaxies is needed to explain a variety of
observational "facts", e.g., the tight relationship between
SMBH mass and host galaxy properties, the galaxy luminosity
function, the absence of significant star formation in
"cooling flow" clusters and groups. Only through X-ray
observations of early-type galaxies, groups, and clusters
that contain hot gaseous atmospheres, that "capture" the
SMBH outburst, can we observe feedback in the present epoch
Universe. We present observations of SMBH outbursts from
galaxies to rich clusters to understand the properties of
these outbursts. We focus on a sample of early type galaxies
(e.g., NGC5813, NGC5846, Fornax A), M87, and compare
outbursts in these systems to those in rich clusters.
