Cool Gas in Clusters of Galaxies

  title={Cool Gas in Clusters of Galaxies},
  author={Megan Donahue and G. Mark Voit},
  journal={arXiv: Astrophysics},
Early X-ray observations suggested that the intracluster medium cools and condenses at the centers of clusters, leading to a cooling flow of plasma in the cluster core. The increased incidence of emission-line nebulosity, excess blue light, AGN activity, and molecular gas in the cores of clusters with short central cooling times seemed to support this idea. However, high-resolution spectroscopic observations from XMM-Newton and Chandra have conclusively ruled out simple, steady cooling flow…

Beyond the Cool Core: The Formation of Cool Core Galaxy Clusters
Why do some clusters have cool cores while others do not? In this paper, cosmological simulations, including radiative cooling and heating, are used to examine the formation and evolution of cool
Cluster temperature profiles and Sunyaev–Zeldovich observations
Galaxy clusters are not isothermal, and the radial temperature dependence will affect the cluster parameters derived through the observation of the Sunyaev-Zeldovich (SZ) effect. We show that the
