DESCRIPTION:The evolution of galaxy clusters is strongly shaped by the phys
 ics of the intracluster medium (ICM)\, where processes such as turbulence\,
  mixing\, and galaxy-ICM interactions drive much of the cluster’s dynamical
  state. One key ingredient is viscosity\, which can suppress small-scale ga
 s motions and modify\ndensity fluctuations and magnetic fields. Yet\, both 
 the strength and nature of viscosity in the ICM remain\nuncertain. In this 
 talk\, I will present results from high-resolution cosmological simulations
  that explicitly include viscosity\, with a particular focus on the Coma cl
 uster. Recent XRISM observations of Coma have revealed unexpectedly low sma
 ll-scale gas motions\, challenging our current understanding of ICM dynamic
 s. I will explore whether viscosity can help explain these observations\, c
 omparing inviscid simulations with models including both isotropic and anis
 otropic viscosity. I will show how these different treatments affect cluste
 r morphology\, turbulence\, and ICM fluctuations\, and discuss how simulati
 ons and observations together can constrain the microphysics of the ICM.\n\
