intracluster medium

(ICM, intracluster gas)
(hot plasma throughout a galaxy cluster)

The intracluster medium (ICM or intracluster gas) is very hot plasma spread throughout a galaxy cluster (most dense in the center), typically hydrogen and helium ions at 10 to 100 megakelvins. A cluster's total ICM mass is more than that of all its stars, but still a fraction of the cluster's dark matter mass. The ICMs of galaxy clusters are X-ray sources.

The term intergalactic medium (IGM) often is used for the ICM, but presumably may be used with the intention of also including any medium between galaxy clusters.
