Scientific paper

The calculations presented suggest that the material stripped from galaxies and gathered in wakes in a rich cluster can only begin to mix efficiently with the surroundings if galaxies actually hit and stir the wakes. A rich cluster's mixing begins after a billion years for r values smaller than R(core), while it takes 10 billion years or more to start the mixing at places with r greater than 2R(core). IGM heating may start flows towards the outskirts, but the timescales required to reach those regions are of Hubble time magnitude or greater. The flows do not, therefore, seem to have any effect on wake dynamics. Iron line observations with high angular resolutions could check the homogeneity of the outskirts, yielding useful data on the gasdynamic state of clusters.
