SUMMARY:Probing Galaxy Cluster Formation Through Dynamics of the Hot\,
  Intracluster Medium (ICM)\, Astronomy Colloquium\, Tom Jones\, Univer
 sity of Minnesota\, School of Physics and Astronomy
DESCRIPTION:Galaxy clusters\, made mostly of dark matter\, are the mos
 t massive and last structures to form out of cosmic expansion. They gr
 ow on timescales of Gyr through accretion and mergers. They are also f
 requently harassed by adjacent\, smaller clumps of dark matter. As a r
 esult of this complex evolution cluster dynamical states are also comp
 lex.The hot ICM plasma is the dominant baryonic cluster component. Bec
 ause the ICM is weakly collisional it effectively captures important d
 etails of the formation dynamics and its history. While some events an
 d processes are revealed conveniently through thermal X-ray emissions\
 , other vital dynamical behaviors are highlighted primarily via non-th
 ermal emissions\, either within the ICM itself or through interactions
  between the ICM and relativistic plasmas deposited within by active g
 alaxies. This non-thermal window into cluster formation dynamics is es
 pecially important in cluster outskirts\, where thermal X-ray signals 
 are weak. In this talk I will review these issues and some of our ongo
 ing efforts to model and decipher distinctive non-thermal signals of I
 CM dynamics.
