Cavities and Sound Waves in the Perseus Cluster
The Perseus Cluster is an example of a black hole blasting out energy and preventing gas from cooling enough to form stars at a high rate. Repeated outbursts from Perseus' central black hole, in the form of powerful jets, create giant cavities and produce shock waves that keep gas warm. This does not appear to be happening in the Phoenix Cluster, at least not to the same degree. Image released August 15, 2012.
South Pole Telescope
The South Pole Telescope (SPT) was used to study the Phoenix Cluster.
