I created this page today; it's a pretty bare-bones overview, but I'd love to see somebody give a little history or examples of relevance. Perhaps when I have more time I can add some of that myself! Motorneuron 17:16, 27 February 2006 (UTC)motorneuron
You say most of the matter is baryons, I thought most of the gravitational matter in a cluster was dark matter. I had learned that the x-ray emitting baryons in the cluster gas were useful because they traced out the gravitational potential created mostly by the dark matter. Maybe you want to look into that further.
You're right that most of the matter in a cluster is dark matter, but the ICM is defined as just being the gas at the center of the cluster. So by definition, we're only looking at the baryons when we talk about the ICM. But the cluster's dark matter still does compose the bulk of its mass.
