    Evidence for AGN Feedback in Galaxy Clusters and Groups by Myriam Gitti, Fabrizio Brighenti, Brian R. McNamara

    Published 2012-01-01
    “…Instead of the initial idea that the thermal gas is cooling and flowing toward the center, the new picture envisages a complex dynamical evolution of the intracluster medium (ICM) regulated by the radiative cooling and the nongravitational heating from the active galactic nucleus (AGN). …”
