Clusters of Galaxies And The Constituents of Material In And Around Clusters of Galaxies

Richard Lieu, Dept. of Physics, University of Alabama in Huntsville

SSL Addition Conference Room at 3pm Tuesday December 18th

Since the mid 1990’s it has been increasingly apparent that material in and around clusters of  galaxies is multi-phased, consisting of dark matter and hot, virialized X-ray emitting gas, and also cooler gases and possibly non-thermal particles. The early evidence for the latter two components was from  EUV and soft X-ray observations from which it was inferred that a warm gas component lies predominantly at the outskirts of the cluster while relativistic particles may exist in the inner parts.
