The Origin of Ripples in Cool Cores of Galaxy Clusters : Heating by MHD Waves ?


We consider MHD waves as a heating source of cool cores of galaxy clusters. In particular, we focus on transverse waves (Alfvén waves), because they can propagate a longer distance than longitudinal waves (sound waves). Using MHD simulations, we found that the transverse waves can stably heat a cool core if the wave period is large enough (& 10 yr… (More)
