“The Intracluster Medium is an incredibly hot, thin gas that fills the cluster and contains magnetic fields and high-speed electrons.”
VERIFIED BY REFERENCE
Wikipedia explicitly describes the intracluster medium as 'superheated plasma' containing ionized hydrogen/helium, magnetic fields, and high-speed electrons. Directly corroborates the claim.
